News and discussions about image sensors

Friday, October 22, 2021 Quantum Dot Sensor Company SWIR Vision Raises $5M in A-RoundOptics.org, EINPressWire:SWIR Vision Systems, a Durham, North Carolina, company developing colloidal quantum dots (CQDs) image sensor has raised $5M in a round A of funding. SWIR Vision Systems has been founded in 2018 as a spin-off from the Research Triangle Institute. The company's Acuros family of thermoelectrically cooled CMOS-based CQD sensors reaches 2.1MP resolution.
While InGaAs SWIR cameras are generally constrained to 640512 or 12801024 pixel formats, our pioneering CQD sensor technology enables 2.1 megapixel, full-HD resolution, the first commercially available SWIR product of its kind.
The new eSWIR version of the product family operates across an extended wavelength range, between 350 nm and 2000 nm, with a pixel pitch of 15 µm.
The company's Vimeo video compares regular RGB imaging with SWIR in foggy environment.

"The performance has been significantly improved compared with the previous generation products. It is equipped with Smartsens' innovative SFCPixel patented technology, which can achieve excellent night vision full-color imaging effects.
In addition, thanks to the PixGain dual-pixel conversion gain technology, SC401AI improves the image quality while further expanding the applicability of terminal products. As a product of the same specification as SC401AI, SC400AI has a frame rate of up to 60fps and can support 30fps dynamic line overlap HDR (Staggered HDR) image output, which provides customers with more choices while imaging performance is upgraded.
Compared with the previous generation products, the full well electrons of SC400AI and SC401AI have increased by 48.6%, the dynamic range has increased by 3dB, and the QE (quantum efficiency) in the 520nm band has increased by 42%."

AAA: New research from AAA finds that moderate to heavy rain affects a vehicle safety systems ability to see, which may result in performance issues. During closed course testing, AAA simulated rainfall and found that test vehicles equipped with automatic emergency braking traveling at 35 mph collided with a stopped vehicle one third (33%) of the time. Lane keeping assistance didnt fare any better with test vehicles departing their lane 69% of the time. Vehicle safety systems, also known as advanced driver assistance systems or ADAS, are typically evaluated in ideal operating conditions. However, AAA believes testing standards must incorporate real-world conditions that drivers normally encounter.

Vehicle safety systems rely on sensors and cameras to see road markings, other cars, pedestrians and roadway obstacles. So naturally, they are more vulnerable to environmental factors like rain, said Greg Brannon, AAAs director of automotive engineering and industry relations. The reality is people arent always driving around in perfect, sunny weather so we must expand testing and take into consideration things people actually contend with in their day-to-day driving.

AnAAA video shows that even a moderate rain interferes with the camera-based emergency braking:

Morimoto/J. Iwata et al.
3D Backside-Illuminated SPAD Imager Sensors: Unlike the CMOS image sensors found in smartphones, which measure the amount of light reaching a sensors pixels in a given timeframe, single photon avalanche diode (SPAD) image sensors detect each photon that reaches the pixel. Each photon is converted into an electric charge, and the electrons that result are eventually multiplied in avalanche fashion until they form an output signal. SPAD image sensors hold great promise for high-performance, low-light imaging applications, for depth sensing, and for fully digital system architectures.
However, until now their performance has been limited by tradeoffs in pixel detection efficiency vs. pixel size, and by poor signal-to-noise ratios. Recently a charge-focusing approach was proposed to overcome these issues, but until now it remained to be implemented. In a late-news paper, Canon researchers will discuss how they did so, with the industrys first 3D-stacked backside-illuminated (BSI) charge-focusing SPADs. The devices featured the largest array size ever reported for a SPAD image sensor (3.2 megapixels) and demonstrated a photon detection efficiency of 24.4%, and timing jitter below 100ps at 940 nm.

"STs Francois Roy succeeds in solid-state image sensors

The International Image Sensor Society recently gave François Roy the Walter Kosonocky Award for his paper entitled Fully Depleted Trench-Pinned Photo Gate for CMOS Image Sensor Applications. The Photo Gate pixel concept improves image quality and the manufacturing process.

It is a great honor for ST, the ST Imaging teams, my PhD students and myself to receive this prestigious award and I thank them all, said François.

At ST we are proud of our inventors. We nurture strong competences and encourage our distinguished senior experts to coach young engineers."

Review of Methods for Resolving Multi-Path Interference in Time-of-Flight Range CamerasAuthor: Refael Whyte, Lee Streeter, Michael Cree, Adrian DorringtonAffiliation: University of Waikato, New Zealand
Abstract: Time-of-Flight (ToF) range cameras measure distance for each pixel by illuminating the entire scene with amplitude modulated light and measuring the change in phase between the emitted light and reflected light. One of the most significant causes of distance accuracy errors is multi-path interference, where multiple propagation paths exist from the light source to the same pixel. These multiple propagation paths can be caused by inter-reflections, subsurface scattering, edge effects and volumetric scattering. Several techniques have been proposed to mitigate multi-path interference. In this paper a review of current techniques for resolving measurement errors due to multi-path interference is presented, as currently there is no quantitative comparison between techniques and evaluation of technique parameters. The results will help with the selection of a multi-path interference restoration method for specific time-of-flight camera applications.

Optimization of Perimeter Gated SPADs in a Standard CMOS ProcessAuthor: Mohammad Habib, Farhan Quaiyum, Syed Islam, Nicole McFarlaneAffiliation: University of Tennessee, Knoxville, United States
Abstract: Perimeter-gated single photon avalanche diodes (PGSPAD) in standard CMOS processes have increased breakdown voltages and improved dark count rates. These devices use a polysilicon gate to reduce the premature breakdown of the device. When coupled with a scintillation material, these devices could be instrumental in radiation detection. This work characterizes the variation in PGSPAD noise (dark count rate) and breakdown voltage as a function of applied gate voltages for varying device shape, size, and junction type.

A Low-Noise High-Sensitivity CMOS Image Sensor for Scientific and Industrial ApplicationsAuthor: Min-Woong Seo, Taishi Takasawa, Keita Yasutomi, Keiichiro Kagawa, Shoji KawahitoAffiliation: Shizuoka University, Japan
Abstract: A low-noise high-sensitivity CMOS image sensor for scientific use is developed and evaluated. The prototype sensor contains 1024(H) 1024(V) pixels with high performance column-parallel ADCs. The measured maximum quantum efficiency (QE) is 69 % at 660 nm and long-wavelength sensitivity is also enhanced with a large sensing area and the optimized process. In addition, dark current is 0.96 pA/cm2 at 292 K, temporal random noise in a readout circuitry is 1.17 electrons RMS, and the conversion gain is 124 uV/e-. The implemented CMOS imager using 0.11-um CIS technology has a very high sensitivity of 87 V/lx*sec that is suitable for scientific and industrial applications such as medical imaging, bioimaging, surveillance cameras and so on.
