Image Sensors World        Go to the original article...

CU Boulder publishes an OSA Optica paper "Time-magnified photon counting with 550-fs resolution" by Bowen Li, Jan Bartos, Yijun Xie, and Shu-Wei Huang.

"Time-correlated single-photon counting (TCSPC) is an enabling technology for applications such as low-light fluorescence lifetime microscopy and photon counting time-of-flight (ToF) 3D imaging. However, state-of-the-art TCSPC single-photon timing resolution (SPTR) is limited to 3–100 ps by single-photon detectors. Here, we experimentally demonstrate a time-magnified TCSPC (TM-TCSPC) that achieves an ultrashort SPTR of 550 fs with an off-the-shelf single-photon detector. The TM-TCSPC can resolve ultrashort pulses with a 130-fs pulse width difference at a 22-fs accuracy. When applied to photon counting ToF 3D imaging, the TM-TCSPC greatly suppresses the range walk error that limits all photon counting ToF 3D imaging systems by 99.2% and thus provides high depth accuracy and precision of 26 µm and 3 µm, respectively."

Image Sensors World        Go to the original article...

Bloomberg reports that Ouster that went public after merging with a SPAC, is in advanced talks to acquire a flash LiDAR startup Sense Photonics.

UKTodayNews quotes Ouster CEO Angus Pacala saying only three to five lidar companies will remain in five years.

Sam Abuelsamid, principal research analyst at Guidehouse Insights, wonder if there’s enough room for the dozens of competitors vying for contracts.

Yole Developpement quotes CEO of XenomatiX Filip Geuens saying that it is now the time for convergence and consolidation in LiDARs: "After a period of intense technology exploration, a time of convergence and consolidation has started. It is becoming more clear which solutions will prevail.

Now it’s a matter of industrializing and letting mature the solutions that have survived the experimental phase."

CNBC: Kyle Vogt, the co-founder and president of Cruise, General Motors’ majority-owned autonomous vehicle subsidiary, is predicting a consolidation/collapse of the lidar industry, specifically regarding companies that have gone public or plan to do so through deals with blank check companies.

Coherent ToF Imager with 250um Depth Resolution

August 24, 2021 By Leave a Comment

Image Sensors World        Go to the original article...

Caltech publishes an arxiv.org paper "IQ Photonic Receiver for Coherent Imaging with a Scalable Aperture" by Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri.

Silicon photonics (SiP) integrated coherent image sensors offer higher sensitivity and improved range-resolution-product compared to direct detection image sensors such as CCD and CMOS devices. Previous generation of SiP coherent imagers suffer from relative optical phase fluctuations between the signal and reference paths, which results in random phase and amplitude fluctuations in the output signal. This limitation negatively impacts the SNR and signal acquisition times. Here we present a coherent imager system that suppresses the optical carrier signal and removes non-idealities from the relative optical path using a photonic in-phase (I) and quadrature (Q) receiver via a 90∘ hybrid detector. Furthermore, we incorporate row-column read-out and row-column addressing schemes to address the electro-optical interconnect density challenge. Our novel row-column read-out architecture for the sensor array requires only 2N interconnects for N2 sensors. An 8×8 IQ sensor array is presented as a proof-of-concept demonstration with 1.2×10−5 resolution over range accuracy. Free-space FMCW ranging with 250um resolution at 1m distance has been demonstrated using this sensor array.

Fight of Velodyne with its Founder Continues

August 24, 2021 By Leave a Comment

Image Sensors World        Go to the original article...

BusinessWire: David Hall, the founder and the largest common stock holder of Velodyne Lidar, Inc. publishes another open letter to the Company’s Board of Directors:

Members of the Board,

I am pleased that following my calls for meaningful leadership changes at Velodyne Lidar, Dr. Anand Gopalan decided to resign as Chief Executive Officer and a director. Though I believe this represents a first step in the right direction, the root of poor business management and the anti-stockholder culture at Velodyne Lidar remains. This is why today, I am calling on Chairman Michael Dee and director Hamid Zarringhalam to resign from the Board. I believe that both of these individuals have breached stockholders’ confidence and destroyed significant value in the Company.

Since being installed on the Board via a merger with Graf Industrial, a special purpose acquisition company (“SPAC”), Mr. Dee has spearheaded major business decisions that leave him responsible for the Company’s nearly 80% stock price decline, in my view. Despite this poor performance and Mr. Dee’s lack of relevant skillsets or public company board experience, the Board recently elevated Mr. Dee to the position of Chairman.

In addition to Mr. Dee’s lack of relevant skillsets to serve on the Board, stockholders should be aware that he is currently deeply embroiled in litigation at PureCycle Technologies, Inc., relating to his role as Chief Financial Officer following its merger with a SPAC with disastrous results. Mr. Dee is facing serious accusations of misleading investors and fraud.

Beyond his unsettling track record, I am deeply concerned that Mr. Dee and the Board are considering transferring Velodyne Lidar’s sophisticated Alpha Prime lidar manufacturing know-how and associated trade secrets, the crown jewels of the Company’s IP portfolio, to Nikon, which is moving into the lidar space with, among other things, its recent partnership with Aeva, a Silicon Valley startup founded to develop lidar technology. I question how moving the best of the Company’s portfolio of technology to Nikon benefits Velodyne’s stockholders whatsoever. It seems as if this move greatly benefits director Hamid Zarringhalam, an executive employee of Nikon, who is acting within a disabling conflict of interest in making decisions that seemingly benefit Nikon, when he should be focused on what is best for Velodyne Lidar and its stockholders.

We are aware that during a recent conversation discussing the decline in Velodyne Lidar’s valuation, Mr. Zarringhalam commented, “I don’t care about the stock decline because I don’t own any.” This statement reveals a complete lack of professionalism and alignment with stockholders. Clearly, the Company is in serious need of ethical directors with public company and high growth tech experience to help turn around the anti-stockholder culture that pervades the current Board.

Update: BusinessWire: Velodyne responds on David Hall open letter:

David Hall is Attempting to Divert Attention from the Ongoing Arbitration Regarding his Theft of Confidential Intellectual Property

The Company believes that Mr. Hall’s actions are an attempt to distract from the serious and ongoing arbitration against Mr. Hall regarding his theft of Velodyne’s confidential, trade secret information. Mr. Hall has never denied taking this confidential, trade secret information, which he seems intent upon using to further his personal business ventures to the detriment of Velodyne and its stockholders.

Like any enterprise with a focus on innovative, breakthrough technologies, Velodyne is committed to protecting its intellectual property. The Company will take any and all actions to ensure Mr. Hall complies with his legal obligations to refrain from any use or disclosure of Velodyne’s property and to immediately return it to Velodyne. The Company views Mr. Hall’s latest missive as an attempt to divert attention from Velodyne’s upcoming proceeding against him, where an initial procedural hearing is set for September 2, 2021.

David Hall Falsely Portrays the Trusted Long-standing Relationship Between Velodyne Lidar and Nikon

The Company’s relationship with Nikon dates back to 2018, when Mr. Hall served as Chief Executive Officer of Velodyne. As part of its long-standing relationship with Velodyne, Nikon has also been a strategic investor in the Company. Today, the Company continues to have a strong partnership with Nikon as a trusted technology and manufacturing partner for Velodyne’s industry-leading lidar sensor.

Michael Dee and Hamid Zarringhalam are Aligned with Velodyne Lidar Stockholders

Michael Dee and Hamid Zarringhalam are independent directors focused on the long-term success of the Company, who have exceptional track records of success as business leaders and have served as outstanding stewards of Velodyne and its stockholders.

Mr. Hall’s fabricated statements about Mr. Zarringhalam are demonstrably false and libelous. Mr. Zarringhalam never made the comments Mr. Hall claimed, and is in fact a stockholder of the Company, having purchased stock using his own personal funds. Mr. Zarringhalam remains a stockholder today and his interests are aligned with those of all stockholders.

Huazhong University of Science and Technology, Wuhan, China, publishes an AIP paper "Photon management with superlattice for image sensor pixels" by  Yuqing Cao,  Zijian Zhang, and Ken Xingze Wang.

"It is important to increase light absorption and quantum efficiency in image sensor pixels, especially for wavelength ranges in which material absorption is weak. Surface textures, including nanostructure lattices, have been invented for significant improvement in light absorption. Those nanostructures typically support a number of physical processes for which the optimal geometries are different. We design a class of nanostructure superlattices to enable the co-optimization of different physical processes for further enhancement in light absorption."

3rd Order Sigma-Delta ADC for Image Sensor

Image Sensors World        Go to the original article...

AMS and Madeira University, Portugal, publish an MDPI paper "Design Improvements on Fast, High-Order, Incremental Sigma-Delta ADCs for Low-Noise Stacked CMOS Image Sensors" by Luis Miguel Carvalho Freitas and Fernando Morgado-Dias.

"It is known that thermal and flicker noise sources are the main contributors to the degradation of the sensor performance, concerning the sensor output image noise. This paper presents an indirect way to reduce both the thermal and the flicker noise contributions by using thin-oxide low voltage supply column readout circuits and fast 3rd order incremental sigma-delta converters with noise shaping capabilities (to provide low noise output digital samples—74 μVrms; 0.7 e−rms; at 105 μV/e−), and thus performing correlated double sampling in a short time (19 μs), while dissipating significant low power (346 μW). Throughout the extensive parametric transistor-level simulations, the readout path produced 1.2% non-linearity, with a competitive saturation capacity (6.5 ke−) pixel. In addition, this paper addresses the readout parallelism as the main point of interest, decoupling resolution from the image noise and the frame rate, at virtually any array resolution."

OSA Optics Express publishes a paper "Broadband responsivity enhancement of Si photodiodes by a plasmonic antireflection bilayer" by Jongcheol Park, Il-Suk Kang, Gapseop Sim, Tae Hyun Kim, and Jong-Kwon Lee from National NanoFab Center and Cheongju University, Korea.

"Randomly distributed plasmonic Ag nanoparticles (NPs) with various sizes were fabricated by a reflow process to an island-shaped Ag thin-film deposited on a Si photodiode. These NPs conformally enclosed by an antireflective (AR)-type SiNx/SiO2 bilayer reveal significantly diminished reflectance in a broad wavelength (500 nm - 1100 nm) as compared to the cases of Ag NPs or SiO2 layer enclosing Ag NPs on the Si substrate. Accordingly, the forward scattering and the total reflection along with wide-angle interference in between the dielectric bilayer incorporating the Ag NPs induce highly increased light absorption in the Si substrate. The fabricated Si photodiode adopting the plasmonic AR bilayer shows the responsivity peak value of 0.72 A/W at 835 nm wavelength and significant responsivity enhancement up to 40% relative to a bare Si photodiode in a wavelength range of 500 nm to 1000 nm."

Yole CIS Market Report: Smaller Companies Expand Market Share

Image Sensors World        Go to the original article...

Yole Developpement publishes an update of its "Status of CMOS Image Sensor Industry 2021 report."  Pierre Cambou, Principal Analyst, reports interesting observations:

"For CIS players, 2020 did not play out similarly to 2019, in fact it was almost the opposite, with the smaller players doing best. Sony didn’t grow, but Samsung grew 13%, OmniVision, Smartsens and SK Hynix grew about 30%, while Galaxycore grew 52% YoY.

The CIS industry output stayed close to its structural limit all through the year, and especially in Q3-2020. For the full year, the whole industry grew by 7.3% YoY in revenue, in line with Yole’s expectation.

Until 2019 mobile device cameras were the main growth contributor to the CIS market. But in 2020 this is no longer the case. Computing, automotive and security market applications have now outpaced the growth of mobile device."

The US$20.7 billion CIS industry is still heavily dominated by mobile and consumer applications, representing more than 72% of revenues. Yet, despite all headwinds in 2020, computing, automotive and security have each grown to similar shares, reaching about 8% of CIS revenues, and 23% combined. They had represented 21% in 2019.

Tower Overviews Optical Fingerprint Technologies

August 10, 2021 By Leave a Comment

Image Sensors World        Go to the original article...

Amos Fenigstein, Managing Director of CIS R&D at Tower, publishes a nice review article "Image Sensors: Leaving Fingerprints Everywhere in the Age of Consumer Data Protection and Security." Few quotes:

There are two major “under screen” optical sensors technologies:
  • a lens-type sensor that uses a system lens and thus uses pixels the size of 5 to 6 microns to resolve the 50um features resolution in the fingerprint, 
  • a 1:1 sensor that does not use a lens and thus, requires large pixels, of around 50um.
The lens-type sensor, if used under LCD, requires an internal light source at the near Infrared regium as the LCD screen is not transparent to visible light. However, if used under OLED, the OLED screen itself acts as the light source and thus, the pixels are required to be sensitive to visible light. This is true for both lens-type sensors and 1:1 sensors under OLED screen (1:1 sensors are not being used under LCD).
The reason to use 1:1 sensors, although it is much larger than a lens-type and as a result are much more costly, is the minimum sensor height that can be achieved only with a lens-less sensor. Such small heights, as small as half a millimeter, is crucial for high end 5G smartphones, where there is only 0.6mm space between the battery on the back and the screen.

Taiwan National Tsing Hua University publishes a paper "A Graphene/Polycrystalline Silicon Photodiode and Its Integration in a Photodiode–Oxide–Semiconductor Field Effect Transistor" by Yu-Yang Tsai, Chun-Yu Kuo, Bo-Chang Li, Po-Wen Chiu, and Klaus Y. J. Hsu.

"The present work reports the observation of the electrical and optoelectronic characteristics of a graphene/polycrystalline silicon junction and explores one possible usage of the junction. The current–voltage curve of the junction was measured to show the typical exponential behavior that can be seen in a forward biased diode, and the photovoltage of the junction showed a logarithmic dependence on light intensity. A new phototransistor named the “photodiode–oxide–semiconductor field effect transistor (PDOSFET)” was further proposed and verified in this work. In the PDOSFET, a graphene/polycrystalline silicon photodiode was directly merged on top of the gate oxide of a conventional metal–oxide–semiconductor field effect transistor (MOSFET). The magnitude of the channel current of this phototransistor showed a logarithmic dependence on the illumination level. It is shown in this work that the PDOSFET facilitates a better pixel design in a complementary metal–oxide–semiconductor (CMOS) image sensor, especially beneficial for high dynamic range (HDR) image detection."
