Panasonic Develops Low-Cost LWIR Lens

January 30, 2022 By Leave a Comment

Image Sensors World        Go to the original article...

Panasonic has developed a mass production technology of low-cost far-IR aspherical lenses. These lenses are made of chalcogenide glass having excellent transmission characteristics in the far-IR. In addition to realizing low-cost (approx. half compared to the company’s conventional method) by newly developed glass molding method and mold processing technology, Panasonic is now able to offer a variety of lenses such as diffractive lens, the world's first* highly hermetic frame-integrated lens without using adhesive (leak detection accuracy of less than 1x10-9 Pa･m3/sec in helium leak test).

A low-cost silicon that has been commonly used as the lens material for far-IR sensors is not suitable for high pixel counts due to its low transmittance, so germanium spherical lenses having high transmittance are widely used as the number of pixels increases. However, as the pixel count increases further, the effect of aberration caused by a spherical lens becomes more pronounced. To reduce this effect, combination of many spherical lenses and an aspherical lens will be required, which leads to increase in cost and size.

To resolve this problem, Panasonic has developed a new technology for the low-cost production of high-performance aspherical lenses suitable for far-infrared optical systems, based on the glass molding technology the company cultivated through the production of visible light aspherical lenses for cameras.

Hermetic sealing is important for thermal imaging camera modules. A low cost lens solution makes thermal cameras more accessible to general consumer applications.

Interview with Sony STARVIS 2 Designers

January 28, 2022 By Leave a Comment

Image Sensors World        Go to the original article...

In June 2021, Sony introduced STARVIS 2 pixel technology for security cameras:

"As the importance of image sensors for security cameras which monitor spaces is growing day by day, the characteristics required of them are also becoming more advanced. Fulfilling all of these requirements, which include low-illuminance performance to allow targets to be discerned even in dark locations, a high dynamic range for face recognition even against a light source such as in entranceways, and performance capable of recording images of moving targets accurately without causing blur or color tints, was a task at a level impossible to accomplish just with improvements to conventional sensors. That is why STARVIS 2 was developed. By redesigning the structure of its image sensor from the ground up, it has successfully implemented characteristics unmatched by any other."



Shimizu：It was triggered by requests from our customers. Although STARVIS had achieved greater low-illuminance sensitivity and improved image quality performance, there were also separate requests to expand its dynamic range so that faces could be accurately recognized even in situations such as entranceways, where the exterior is bright and shooting images against that light source causes faces to become dark and shadowed. Development on STARVIS 2 began to answer these requests.

Shirahama：Normally, we move on to commercialization only after a product’s technology is in place, but since both proceeded simultaneously in this case, we were required to execute development and testing in extremely short cycles. We had no choice but to move forward while resolving each issue one at a time. Because of these conditions, the first prototype was full of problems and was completed in a state that was entirely unacceptable for commercialization.
However, since there was no leeway in the commercialization schedule, delays were not something that could be allowed easily, so the question of how to move the overall project forward while staying aware of its issues was very important. Even when we thought “It’s no use anymore,” we kept an eye on the schedule while resolving each problem, and took one step ahead at a time. And as we did so, our thoughts of “It’s no use anymore” gradually changed more and more into feelings of “Maybe it will work!” Even though the team for this project consisted of members working together for the first time, they possessed the capabilities to solve issues and the flexibility to skillfully move the project forward even under its strict schedule. I began to think “This just may be an incredible team” and working with the team became more and more enjoyable. One of the unique experiences that arose during this project was that as it went forward, the trust we felt toward our team grew and grew.


Kawamura：As our development policy, we are constantly making product improvements while maintaining the strengths of the products. This time, in order to address the issue of expanding the dynamic range, there was a need to increase the saturation of the photodiode. Therefore, instead of attaching the photodiode to a conventional silicon surface, we developed a structure which accumulated electric charge in the vertical direction within the silicon.

At the same time, we also introduced new technology for a high dynamic range feature.

We had to proceed with the development of these two new structures that had not yet been established while staying within the schedule for commercialization, so it was a challenge under an extremely tight development period. As Shirahama-san mentioned earlier, there were problems with charge transfer in the initial prototype and it was full of issues, so we were not able to even sufficiently evaluate them.

Iwabuchi：This vertical-structure photodiode had not yet been applied to image sensors, so it was a technology with high risks regarding mass production. Still, we desperately needed a form of breakthrough technology to achieve a wider dynamic range, so since there was a section for prototypes on the development line at Atsugi TEC, we started by trying it out there. We proceeded step-by-step starting from verifying its principles as we marked each development milestone. The commercialization schedule this time had been formulated under the assumption that all parts of technological development would proceed smoothly. As we were faced with successive issues from the very start that did not go as planned, we were continually walking a tightrope to figure out how we could somehow maintain the development schedule.


Iwabuchi：To expand the dynamic range, we had to increase the saturation signal while also suppressing noise.
The new vertical structure adopted this time was an innovative structure that could increase the saturation signal amount, but we faced tremendously difficult struggles to optimize the process conditions so that those increased signals could be transmitted reliably.
Regarding the other matter of noise suppression, since both the structure and process were new, we were thoroughly aware of the possibility that the dark characteristics, which were the cause of noise, might become worse.
In order to simultaneously resolve the two issues of increasing the saturation capacity while suppressing noise, we implemented various measures such as reviewing the pixel layout and process conditions, and finally succeeded in developing characteristics to obtain image quality that would fulfill the requests of our customers.

Kawamura：In this project, we made a change to a new pixel structure, but I believe it is still just the beginning. Changing the photodiode to a vertical configuration to make it possible to increase the saturation capacity for greater depth has an enormous amount of hidden potential. I believe it will become essential in the security field to improve image recognition rates, so we intend to further enhance our pixel characteristics such as infrared sensitivity and high dynamic range while also miniaturizing pixels, to make our range of image sensor applications wider than ever before.

Iwabuchi：I believe that Sony’s strengths lie in its ability to carry out advanced development of image sensors with unequaled characteristics that use processes which cannot be copied by competitors, like STARVIS 2. Sony has an atmosphere which encourages new internal challenges, and its engineers in each field are full of motivation to try new things. I hope that we will be able to fully apply the advantages of this environment, to continue to develop revolutionary image sensors distinctive to Sony which are the first of their kind in the world.

iToF: Comparison of Different Multipath Resolve Methods

January 27, 2022 By Leave a Comment

Image Sensors World        Go to the original article...

IEEE Sensors publishes a video presentation "Multi-Layer ToF: Comparison of Different Multipath Resolve Methods for Indirect 3D Time-of-Flight" by Jonas Gutknecht and Teddy Loeliger from ZHAW School of Engineering, Switzerland.

Abstract: Multipath Interferences (MPI) represent a significant source of error for many 3D indirect time-of-flight (iToF) applications. Several approaches for separating the individual signal paths in case of MPI are described in literature. However, a direct comparison of these approaches is not possible due to the different parameters used in these measurements. In this article, three approaches for MPI separation are compared using the same measurement and simulation data. Besides the known procedures based on the Prony method and the Orthogonal Matching Pursuit (OMP) algorithm, the Particle Swarm Optimization (PSO) algorithm is applied to this problem. For real measurement data, the OMP algorithm has achieved the most reliable results and reduced the mean absolute distance error up to 96% for the tested measurement setups. However, the OMP algorithm limits the minimal distance between two objects with the setup used to approximately 2.7 m. This limitation cannot be significantly reduced even with a considerably higher modulation bandwidth.

Facebook Proposes Image Sensing for More Accurate Voice Recognition

January 25, 2022 By Leave a Comment

Image Sensors World        Go to the original article...

Meta (Facebook) publishes a research post "AI that understands speech by looking as well as hearing:"

"People use AI for a wide range of speech recognition and understanding tasks, from enabling smart speakers to developing tools for people who are hard of hearing or who have speech impairments. But oftentimes these speech understanding systems don’t work well in the everyday situations when we need them most: Where multiple people are speaking simultaneously or when there’s lots of background noise. Even sophisticated noise-suppression techniques are often no match for, say, the sound of the ocean during a family beach trip or the background chatter of a bustling street market.

To help us build these more versatile and robust speech recognition tools, we are announcing Audio-Visual Hidden Unit BERT (AV-HuBERT), a state-of-the-art self-supervised framework for understanding speech that learns by both seeing and hearing people speak. It is the first system to jointly model speech and lip movements from unlabeled data — raw video that has not already been transcribed. Using the same amount of transcriptions, AV-HuBERT is 75 percent more accurate than the best audio-visual speech recognition systems (which use both sound and images of the speaker to understand what the person is saying)."

Thesis on SPAD Quenching

Image Sensors World        Go to the original article...

University of Paris-Saclay publishes o PhD thesis "Modeling and simulation of the electrical behavior and the quenching efficiency of Single-Photon Avalanche Diodes" by Yassine Oussaiti.

"Single-photon avalanche diodes (SPADs) emerged as the most convenient photodetectors for many photon-counting applications, taking advantage of their high detection efficiencies and fast timing responses. Over the past years, their design rules have been evolving to reach more aggressive performances. Usually, trade-offs are required to meet the different constraints.To face these technological challenges, the development of reliable models to describe the device operation and predict the relevant figures-of-merit is compulsory. Evidently, the numerical solvers must be both physics-based and computationally efficient.This Ph.D. work aims to improve the modeling of silicon SPADs, focusing on the avalanche build-up and the quenching efficiency. After a state-of-the-art overview, we investigate various device architectures and potential technological improvements using TCAD methods. We highlight the role of calibrated models and scalability laws in predicting the electrical response.Furthermore, we present a Verilog-A model accounting for the temporal current build-up in SPADs. The important parameters of this model are fitted on TCAD mixed-mode predictions. Importantly, the resulting SPICE simulations of the quenching compare favorably with measurements, allowing a pixel designer to optimize circuits.Since standard TCAD tools are based on deterministic models, the stochastic description of carriers is limited. Hence, Monte Carlo algorithms are used to simulate the statistical behavior of these photodiodes, with a particular attention on the photon detection efficiency and timing jitter. The good agreement between simulation results and experiments confirms the method's accuracy, and demonstrates its ability to assist the development of new generation SPADs."

Image Sensors World        Go to the original article...

Toulouse University publishes a PhD thesis "Developing a method for modeling, characterizing and mitigating parasitic light sensitivity in global shutter CMOS image sensors" by Federico Pace.

"Though being treated as a figure of merit, there is no standard metric for measuring Parasitic Light Sensitivity in Global Shutter CMOS Image Sensors. Some measurement techniques have been presented in literature [Mey+11], though they may not apply for a general characterization of each pixel in the array. Chapter 4 presents a development of a standard metric for measuring Parasitic Light Sensitivity in Global Shutter CMOS Image Sensors that can be applied to the large variety of Global Shutter CMOS Image Sensors on the market.

The metric relies on Quantum Efficiency (QE) measurements, which are widely known in the image sensor community and well standardized. The metric allows per-pixel characterization at different wavelength and at different impinging angles, thus allowing a more complete characterization of the Parasitic Light Sensitivity in Global Shutter CMOS Image Sensors."

Image Sensors World        Go to the original article...

EPFL and Glasgow University publish an Optics Express paper "Light detection and ranging with entangled photons" by Jiuxuan Zhao, Ashley Lyons, Arin Can Ulku, Hugo Defienne, Daniele Faccio, and Edoardo Charbon.

"Single-photon light detection and ranging (LiDAR) is a key technology for depth imaging through complex environments. Despite recent advances, an open challenge is the ability to isolate the LiDAR signal from other spurious sources including background light and jamming signals. Here we show that a time-resolved coincidence scheme can address these challenges by exploiting spatio-temporal correlations between entangled photon pairs. We demonstrate that a photon-pair-based LiDAR can distill desired depth information in the presence of both synchronous and asynchronous spurious signals without prior knowledge of the scene and the target object. This result enables the development of robust and secure quantum LiDAR systems and paves the way to time-resolved quantum imaging applications."

AIT Austrian Institute of Technology, ETH Zurich, Western Sydney University, and University of Illinois at Urbana-Champaign publish a pre-print paper "Bio-inspired Polarization Event Camera" by Germain Haessig, Damien Joubert, Justin Haque, Yingkai Chen, Moritz Milde, Tobi Delbruck, and Viktor Gruev

"The stomatopod (mantis shrimp) visual system has recently provided a blueprint for the design of paradigm-shifting polarization and multispectral imaging sensors, enabling solutions to challenging medical and remote sensing problems. However, these bioinspired sensors lack the high dynamic range (HDR) and asynchronous polarization vision capabilities of the stomatopod visual system, limiting temporal resolution to ~12 ms and dynamic range to ~ 72 dB. Here we present a novel stomatopod-inspired polarization camera which mimics the sustained and transient biological visual pathways to save power and sample data beyond the maximum Nyquist frame rate. This bio-inspired sensor simultaneously captures both synchronous intensity frames and asynchronous polarization brightness change information with sub-millisecond latencies over a million-fold range of illumination. Our PDAVIS camera is comprised of 346x260 pixels, organized in 2-by-2 macropixels, which filter the incoming light with four linear polarization filters offset by 45 degrees. Polarization information is reconstructed using both low cost and latency event-based algorithms and more accurate but slower deep neural networks. Our sensor is used to image HDR polarization scenes which vary at high speeds and to observe dynamical properties of single collagen fibers in bovine tendon under rapid cyclical loads."

Tower publishes a MDPI paper "Embedded UV Sensors in CMOS SOI Technology" by Michael Yampolsky, Evgeny Pikhay, and Yakov Roizin.

"We report on ultraviolet (UV) sensors employing high voltage PIN lateral photodiode strings integrated into the production RF SOI (silicon on isolator) CMOS platform. The sensors were optimized for applications that require measurements of short wavelength ultraviolet (UVC) radiation under strong visible and near-infrared lights, such as UV used for sterilization purposes, e.g., COVID-19 disinfection. Responsivity above 0.1 A/W in the UVC range was achieved, and improved blindness to visible and infrared (IR) light demonstrated by implementing back-end dielectric layers transparent to the UV, in combination with differential sensing circuits with polysilicon UV filters. Degradation of the developed sensors under short wavelength UV was investigated and design and operation regimes allowing decreased degradation were discussed. Compared with other embedded solutions, the current design is implemented in a mass-production CMOS SOI technology, without additional masks, and has high sensitivity in UVC."

Recently, reconstruction-based spectrometers have gained popularity for their compact size, easy maneuverability, and versatile utilities. These devices exploit the superior computational capabilities of recent computers to reconstruct hyperspectral images using detectors with distinct responsivity to different wavelengths. In this paper, we propose a CMOS compatible reconstruction-based on-chip spectrometer pixels capable of spectrally resolving the visible spectrum with 1 nm spectral resolution maintaining high accuracy (>95 %) and low footprint (8 um x 8 um), all without the use of any additional filters. A single spectrometer pixel is formed by an array of silicon photodiodes, each having a distinct absorption spectrum due to their integrated nanostructures, this allows us to computationally reconstruct the hyperspectral image. To achieve distinct responsivity, we utilize random photon-trapping nanostructures per photodiode with different dimensions and shapes that modify the coupling of light at different wavelengths. This also reduces the spectrometer pixel footprint (comparable to conventional camera pixels), thus improving spatial resolution. Moreover, deep trench isolation (DTI) reduces the crosstalk between adjacent photodiodes. This miniaturized spectrometer can be utilized for real-time in-situ biomedical applications such as Fluorescence Lifetime Imaging Microscopy (FLIM), pulse oximetry, disease diagnostics, and surgical guidance."
