Metalenz Launches Polar ID, Enabling Simple, Secure Face Unlock for Smartphones 

  • The world’s first polarization sensor for smartphones, Polar ID provides ultra-secure facial authentication in a condensed footprint, lowering implementation cost and complexity.
  •  Now demonstrated on Qualcomm Technologies’ latest Snapdragon mobile platform, Polar ID is poised to drive large-scale adoption of secure face unlock across the Android ecosystem.

Boston, MA – October 26, 2023 Meta-optics industry leader Metalenz unveiled Polar ID, a revolutionary new face unlock solution, at Qualcomm Technologies’ annual Snapdragon Summit this week. Being the world’s only consumer-grade imaging system that can sense the full polarization state of light, Polar ID enables the next level of biometric security. Using breakthrough advances in meta-optic capability, Polar ID accurately captures the unique “polarization signature” of a human face. With this additional layer of information, even the most sophisticated 3D masks and spoof instruments are immediately detected as non-human.


Facial authentication provides a seamless method for unlocking phones and allowing digital payment. However, to make the solution sufficiently secure requires expensive, bulky, and often power-hungry optical modules. Historically, this has limited the implementation of face unlock to only a few high-end phone models. Polar ID harnesses meta-optic technology to extract additional information such as facial contour details and to detect human tissue liveness from a single image. It is significantly more compact and cost effective than incumbent “Structured Light” face authentication solutions which require an expensive dot-pattern projector and multiple images.


Now demonstrated on a smartphone reference design powered by the new Snapdragon® 8 Gen 3 Mobile Platform, Polar ID has the efficiency, footprint, and price point to enable any Android smartphone OEM to bring the convenience and security of face unlock to the 100s of millions of mobile devices that currently use fingerprint sensors.

“Size, cost, and performance, those are the key metrics in the consumer industry”, said Rob Devlin, Metalenz CEO & Co-founder. “Polar ID offers an advantage in all three. Its small enough to fit in the most challenging form factors, eliminating the need for a large notch in the display. Its secure enough that it doesn’t get fooled by the most sophisticated 3D masks. Its substantially higher resolution than existing facial authentication solutions, so even if you’re wearing sunglasses and a surgical mask, the system still works. As a result, Polar ID delivers secure facial recognition at less than half the size and cost of incumbent solutions.”


“With each new generation of our flagship Snapdragon 8 series, our goal is to deliver the next generation of cutting-edge smartphone imaging capabilities to consumers. Our advanced Qualcomm® Spectra™ ISP and Qualcomm® Hexagon™ NPU were specifically designed to enable complex new imaging solutions, and we are excited to work with Metalenz to support their new Polar ID biometric imaging solution on our Snapdragon mobile platform for the first time,” said Judd Heape, VP of Product Management, Qualcomm Technologies, Inc.


“Polar ID is a uniquely powerful biometric imaging solution that combines our polarization image sensor with post-processing algorithms and sophisticated machine learning models to reliably and securely recognize and authenticate the phone’s registered user. Working closely with Qualcomm Technologies to implement our solution on their reference smartphone powered by Snapdragon 8 Gen 3, we were able to leverage the advanced image signal processing capabilities of the Qualcomm Spectra ISP while also implementing mission critical aspects of our algorithms in the secure framework of the Qualcomm Hexagon NPU, to ensure that the solution is not only spoof-proof but also essentially unhackable” said Pawel Latawiec, CTO of Metalenz. “The result is an extremely fast and compute efficient face unlock solution ready for OEMs to use in their next generation of Snapdragon 8 Gen 3-powered flagship Android smartphones.”


Polar ID is under early evaluation with several top smartphone OEMs, and additional evaluation kits will be made available in early 2024. Metalenz will exhibit its revolutionary Polar ID solution at MWC Barcelona and is now booking meetings to showcase a live demo of the technology to mobile OEMs.

Kevin Boyle, CEO & Founder
 

XPERI
“Privacy continues to be one of the biggest consumer concerns when vision-based technology is used in our products such as DMS and TV services. Prophesee’s event-based Metavision technology enables us to take our ‘privacy by design’ principle to an even more secure level by allowing scene understanding without the need to have explicit visual representation of the scene. By capturing only changes in every pixel, rather than the entire scene as with traditional frame-based imaging sensors, our algorithms can derive knowledge to sense what is in the scene, without a detailed representation of it. We have developed a proof-of-concept demo that demonstrates DMS is fully possible using neuromorphic sensors. Using a 1MP neuromorphic sensor we can infer similar performance as an active NIR illumination 2MP vision sensor-based solution. Going forward, we focus on the GenX320 neuromorphic sensor that can be used in privacy sensitive smart devices to improve user experience.”

Sony Semiconductor Solutions to Launch 1/3-Type-Lens-Compatible, 3.2-Effective-Megapixel Stacked CMOS Image Sensor with Global Shutter for Industrial Use Featuring Highest Resolution in This Class in the Industry

Atsugi, Japan — Sony Semiconductor Solutions Corporation (SSS) today announced the upcoming release of the IMX900, a 1/3-type-lens-compatible, 3.2-effective-megapixel stacked CMOS image sensor with a global shutter for industrial use that boasts the highest resolution in its class.
The new sensor product employs an original pixel structure to dramatically improve light condensing efficiency and near infrared sensitivity compared to conventional products, enabling miniaturization of pixels while maintaining the key characteristics required of industrial image sensors. This design achieves the industry’s highest resolution of 3.2 effective megapixels for a 1/3.1-type, global shutter system which fits in the S-mount (M12), the mount widely used in compact industrial cameras and built-in vision cameras.

The new product will contribute to the streamlining of industrial tasks in numerous ways, by serving in applications such as code reading in the logistics market and assisting in automating manufacturing processes using picking robot applications on production lines, thereby helping to resolve issues in industrial applications.

With demand for automation and manpower savings on the rise in every industry, SSS’s original Pregius S™ global shutter technology contributes to improved image recognition by enabling high-speed, high-precision, motion distortion-free imaging in a compact design. The new sensor utilizes a unique pixel structure developed based on Pregius S, moving the memory unit that was previously located on the same substrate as the photodiode to a separate signal processing circuit area. This new design makes it possible to enlarge the photodiode area, enabling pixel miniaturization (2.25 μm) while maintaining a high saturation signal volume, successfully delivering a higher pixel count of approximately 3.2 effective megapixels for a 1/3.1-type sensor.

Moving the memory unit to the signal processing circuit area has also increased the aperture ratio, bringing significant improvements to both incident light angle dependency and quantum efficiency. These features enable a much greater level of flexibility in the lens design for the cameras which employ this sensor. Additionally, a thicker photodiode area enhances the near infrared wavelength (850 nm) sensitivity, and nearly doubles the quantum efficiency compared to conventional products.

This compact, 1/3.1-type product is available in a package size that fits in the S-mount (M12), the versatile mount type used in industrial applications. It can be used in a wide range of applications where more compact, higher performance product designs are desired, such as in compact cameras for barcode readers in the logistics market, picking robot cameras on production lines, and the automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) that handle transportation tasks for workers.

Main Features

  •  Industry’s highest resolution for an image sensor with a global shutter compatible with a 1/3-type lens, at approximately 3.2 effective megapixels
  •  Vastly improved incident light angle dependency lend greater flexibility to lens design

Reticon-PerkinElmer-Excelitas Documentation

Image Sensors World        Go to the original article...

This entry covers the progression of products originally developed by Reticon through its acquisition by EG&G (retaining the Reticon name) then EG&G's acquisition of part of PerkinElmer and the PerkinElmer name (Reticon was still applied sporadically as a brand) and finally the spinoff of PerkinElmer's optoelectronics businesses as Excelitas. Throughout this process, many of the original Reticon products retained their original part numbers as can be seen in the data sheets. 

Four items of note:

1 - Documents issued under "EG&G Reticon" are in the Reticon folder since the Reticon identity was maintained.  There is not yet an EG&G folder but this will be added when the amorphous silicon flat-panel products developed by EG&G are covered. The EG&G Amorphous Silicon facility was in the same building as Reticon in Sunnyvale, California, but operated independently. That business was later sold by PerkinElmer to Varex, formerly Varian Medical Systems.

2 - Excelitas no longer sells any Reticon-originated products. These became difficult to source when the fab Reticon operated in its own building was closed in the late 90's. Moving from a 3 micron process to 180 nm was quite difficult, especially while the selection of fabs who could make CCDs was rapidly shrinking. Excelitas still sells products originally made by some of the other optoelectronics companies EG&G bought, like thermopile arrays.  Those are included in the Excelitas folder but their history will be told later.

3 - Reticon, up through the PerkinElmer days, made many custom devices including a 20,000 pixel long three-color TDI sensor that flew on the U2 and an ultraviolet CCD for i-line semiconductor mask inspection. If the specifications or evaluation reports for any of these turn up, they will be posted.

4 - Reticon started by making bucket-brigade devices to be used as delay lines and switched-capacitor filter chips. These aren't imagers but they are in the folder to provide some background.

Galaxycore announces dual analog gain HDR CIS

Image Sensors World        Go to the original article...

Press release: https://en.gcoreinc.com/news/detail-66

GalaxyCore Unveils Industry's First DAG Single-Frame HDR 13Megapixels CIS

2023.08.11

GalaxyCore has officially launched the industry's first 13megapixels image sensor with Single-Frame High Dynamic Range (HDR) capability – the GC13A2. This groundbreaking 1/3.1", 1.12μm pixel back-illuminated CIS features GalaxyCore's unique Dual Analog Gain (DAG) circuit architecture, enabling low-power consumption 12bit HDR output during previewing, photography, and video recording. This technology enhances imaging dynamic range for smartphones, tablets, and more, resulting in vividly clear images for users.

The GC13A2 also supports on-chip Global Tone Mapping, which compresses real-time 12bit data into 10bit output, preserving HDR effects and expanding compatibility with a wider range of smartphone platforms.



High Dynamic Range Technology

Dynamic range refers to the range between the darkest and brightest images an image sensor can capture. Traditional image sensors have limitations in dynamic range, often failing to capture scenes as perceived by the human eye. High Dynamic Range (HDR) technology emerged as a solution to this issue.


Left Image: blowout in the bright part resulting from narrow dynamic range/Right Image: shot with DAG HDR

Currently, image sensors use multi-frame synthesis techniques to enhance dynamic range:
Photography: Capturing 2-3 frames of the same scene with varying exposure times – shorter exposure to capture highlight details and longer exposure to supplement shadow details – then combining them to create an image with a wider dynamic range.

Video Recording: Utilizing multi-frame synthesis, the image sensor alternates between outputting 60fps long-exposure and short-exposure images, which the platform combines to produce a 30fps frame with preserved highlight color and shadow details. While multi-frame synthesis yields noticeable improvements in dynamic range, it significantly increases power consumption, making it unsuitable for prolonged use on devices like smartphones and tablets. Moreover, it tends to produce motion artifacts when capturing moving objects.

GalaxyCore's Patented DAG HDR Technology

GalaxyCore's DAG HDR technology, based on single-frame imaging, employs high analog gain in shadow regions for improved clarity and texture, while low analog gain is used in highlight parts to prevent overexposure and preserve details. Compared to traditional multi-frame HDR, DAG HDR not only increases dynamic range and mitigates artifact issues but also addresses the power consumption problem associated with multi-frame synthesis. For instance, in photography, scenes that used to require 3-frame synthesis are reduced by 50% when utilizing DAG HDR.

Left Image: Traditional HDR Photography Right Image: DAG HDR Photography

GC13A2 Empowers Imaging Excellence with HDR


Empowered by DAG HDR, the GC13A2 is capable of low-power 12bit HDR image output and 4K 30fps video capture. It reduces the need for frame synthesis during photography and lowers HDR video recording power consumption by approximately 30%, while avoiding the distortion caused by motion artifacts.

Compared to other image sensors of the same specifications in the industry, GC13A2 supports real-time HDR previewing, allowing users to directly observe every frame's details while shooting. This provides consumers with an enhanced shooting experience.

GC13A2 has already passed initial verification by brand customers and is set to enter mass production. In the future, GalaxyCore will introduce a series of high-resolution DAG single-frame HDR products, including 32Megapixels and 50Megapixels variants. This will further enhance GalaxyCore’s high-performance product lineup, promoting superior imaging quality and an enhanced user experience for smartphones.

MDPI IISW2023 special issue – 316MP, 120FPS, HDR CIS

Image Sensors World        Go to the original article...

A. Agarwal et al. have published a full length article on their IISW 2023 conference presentation in a special issue of MDPI Sensors. The paper is titled "A 316MP, 120FPS, High Dynamic Range CMOS Image Sensor for Next Generation Immersive Displays" and is joint work between Forza Silicon (AMETEK Inc.) and Sphere Entertainment Co..

Full article (open access): https://doi.org/10.3390/s23208383

Abstract
We present a 2D-stitched, 316MP, 120FPS, high dynamic range CMOS image sensor with 92 CML output ports operating at a cumulative date rate of 515 Gbit/s. The total die size is 9.92 cm × 8.31 cm and the chip is fabricated in a 65 nm, 4 metal BSI process with an overall power consumption of 23 W. A 4.3 µm dual-gain pixel has a high and low conversion gain full well of 6600e- and 41,000e-, respectively, with a total high gain temporal noise of 1.8e- achieving a composite dynamic range of 87 dB.

Tektronix and SITe Documentation

Image Sensors World        Go to the original article...

Tektronix and SITe are posted together because one transformed into the other carrying along the existing fab, products and people. Tektronix (yes, the oscilloscope company) originally worked in CCDs to produce a delay line use to convert a fast data stream into a slower one for an oscilloscope designed to capture high-speed transients. Tek decided to use its CCD technology to make large sensors for astronomy and medicine. Making imaging devices was an odd business for them so they sold it to an investment company which, in October 1993, formed Scientific Imaging Technologies. SITe supplied big CCDs into the early 2000s.
