Chair's opening remarks
A new growth cycle for the CMOS image sensor industry
After having achieved $21.3B revenues in 2021, a similar limited growth pattern is expected for 2022 with 2.4% YoY. How will the CMOS image sensor industry come back to a steady expansion and the promise to pass the $30B revenues by 2028? Indeed, a new growth cycle is coming, supported not only by the opportunities in mobile and its multi-cameras approach, but also other applications for consumer, automotive, security and industrial. Investments in capacity and R&D are shaping the competitive landscape. Technology trends, including evolution in the sensor and logic stacking process, and emerging technologies such as metasurface devices and new imaging approaches will also be discussed.

Keynote: Teledyne's expanding vision - from sensing to decision support
Towards hybrid event/image vision
Event Vision Sensors (EVS) determine at a pixel level whether a temporal contrast change beyond a predefined threshold is detected. Compared to CMOS image sensors (CIS) this new modality inherently provides data-compression functionality and hence, enables high-speed, low latency data capture while operating at low power. Numerous applications such as object tracking, 3D detection, or slow-motion are being researched based on EVS. Many applications require EVS sensors to be complemented by CIS information in order to get absolute measurements of the illuminance. Dual sensor configurations have several shortcomings, such as the parallax error of the camera collocation, the complexities in synchronization and added cost – e.g. through the need for two pairs of lenses, packages etc. Advanced wafer-level stacking technology allows for high resolution EVS functionality without severely sacrificing CIS performance. This talk will introduce OMNIVISION’s hybrid sensor technology and outline crucial aspects to be considered for enabling novel hybrid use-cases.

From 3D stacking to 3D CMOS image sensors: evolution, challenges and directions for manufacturing technologies and pixel architectures
CMOS Image sensors have evolved beyond passive 2D image capture to active decision making. Depth sensing has increased the accuracy of information and opened new application opportunities.

Pixel architectures have diversified from rolling shutters to differentiated sensors:
  • Global shutter pixels embedding memory
  • Direct and indirect time of flight based on single photon avalanche detection or fast photodiodes
  • Native high-dynamic-range pixels combining both electron and hole sensing.
The optical spectrum has also spread from visible to infrared, towards longer wavelengths for safety and power saving reasons. The new pixels deliver highly sought-after pitch reduction and can be optimized for new market opportunities. Some of the fundamental technologies for high performance pixels include deep isolation trenches, wafers stacking, optimizing diodes and transfer gates, and QE enhancement with silicon structuration. We are also researching opportunities to increase sensitivity through new materials like quantum dots to improve QE and density.

Detector developments for current and future ESA missions - challenges and opportunities
European Space Agency has an on-going interest in the further development and optimization of detectors across the waveband for space instrumentation. Detectors form a cornerstone in the measurement capabilities of space missions sensing radiation from Infrared to X-rays and beyond, and consequently the Agency is always concerned to have the highest possible detector performance available to instrument developers.

With a particular interest of upcoming missions in the infrared wavebands, ESA is pursuing a number of significant development programs aimed at ensuring the availability of suitable detection systems for these activities. For scientific space applications in the visible, contrary to many other fields of operation, CCDs continue to dominate, with this mature technology at the point where a fully customized and optimized design is pursued on a mission by mission basis. That being said, the Agency also recognizes the future role that CMOS image sensors will play and is actively pursuing the development of the technology building blocks necessary to make such detectors available to future instrumentation.

In this talk, the status of current detector and detector related development activities supported by the European Space Agency will be discussed.

C100, a novel CMOS detector optimised for 100 keV Cryo electron microscopy
Recent years have seen an explosion in the use of electron cryomicroscopy for determination of the structure of biological samples. CryoEM systems at 300keV can be expensive and recent publications suggest that in many cases the information recovered per unit damage could be 25% greater using cost effective 100 keV systems. C100 is a novel detector optimised for 100keV electrons. It contains a CMOS sensor with 2kx2k pixels with 54um pitch, 2000fps readout with 12b resolution which maximises performance in integrating and counting mode. We present results of the characterisation the sensor using 100keV electrons, with DQE, MTF and Landau plots.

Virtually integrating microbolometer (deblurring thermal imagers)
Microbolometers are found in the low-end price segment of thermal imaging systems; they are relatively cheap and accurate, but have their limits, one of which is the time constant of the sensor, causing motion blur. This is a problem in every scenario where movement is in the image, being it mounted to a car or otherwise looking at movement.

The presentation will describe a method for mathematically converting a microbolometer into an integrating sensor, making it behave like a standard rolling shutter sensor with an acquisition time equal to its frame time. Up to a limit reducing the frame time, or increasing the frame rate, will further reduce motion artifacts in the image, reaching for virtual time constants below 1ms.
This allows the usage of the cheap bolometer sensors in applications where up to now cooled thermal imagers were the only option.

Temperature dependence of performance parameters of a CMOS image sensor
In this presentation various performance parameters of an existing, commercially available image sensor will be discussed as a function of temperature.  A temperature range from -30 deg.C to +70 deg.C will be used.  The following characteristics will be highlighted : conversion gain, temporal noise (total, row, column), fixed-pattern noise (total, row, column), dark current, light sensitivity, PRNU, full-well capacity, maximum signal-to-noise ratio, dynamic range and non-linearity.  Some of these parameters hardly depend on the temperature, others strongly change with temperature, and not all of them have a positive temperature coefficient.

Pixel based machine learning enabled true CNN "always on" functionality
Digital systems typically struggle to provide an “always on“ operation because of the need to continuously poll, digitize and analyze data quickly enough not to miss a transaction or seem slow to function, especially when they contain an analog sensor. The sensors are the system's eyes, ears and fingers. Sensors can focus on what we care about and ignore the rest – a face, another car, an intruder, a sound, a change. Next generation sensors, for the first time, are becoming smart enough to deal with events, make decisions, and perform complex analysis. This is the future of sensors.

SWIR CQD photodiode arrays for global shutter sensors, 3D imaging, and multispectral detection in industrial, automotive, consumer, and health monitoring applications
The SWIR band from 1000-2400 nm offers opportunities for optical systems that are not available to visible and near infrared-based systems. These advantages arise from the increased transmission of longer wavelength photons through scattering obscurants, plastics, silicon, and OLED backplanes; higher eye safety thresholds for SWIR-based lasers; and the ability to detect infrared spectral signals for important chemical signatures such as skin, glucose, and hydrocarbons. SWIR Vision will provide an overview of their approach to building CQD-based sensors and how it enables applications requiring small pixel pitch, CMOS-competitive pricing, and high-speed detection.

A new paradigm of sensors working across all lighting environments
Recent advances in the development of image sensors and laser sources are sparking new innovations in the field of depth sensing. These advances enable the design of 3D cameras with high ambient light tolerance up to an operating range of 25 meters. This combination of performance features is essential for effective AI/ML applications in daylight conditions. This new generation of 3D cameras will not only change the industry standard for mid-range ambient light tolerance but will also usher in a new paradigm of sensors working across all lighting environments. An overview of the respective technologies, their current product development status, and their performance data are discussed.

Image and depth in one shot: a single-lens 3D camera and its applications
Combined 2 and 3D sensing eliminates the need for complex image and depth matching algorithms in the reconstruction of real objects and scenes. Seamless image and depth perception is also a requirement for millimetre and submillimetre scale metrology and inspection and for immersive AR applications such as lip tracking as well as applications in health care. We introduce a compact single shot depth sensor based on innovative optics and advanced algorithms that simultaneously capture a 2D image and a depth map in real time for perfectly matched image and depth (at 30, 60 and 90 frames per second). This approach consumes very low power (250 mW) within a miniaturized 3D-camera.

Physics-based model of CMOS for complete camera system simulation
As cameras continue to increase in popularity for various applications from mobile assistants to autonomous driving and augmented reality, designers face shortened design cycles that require more efficient design and simulation processes. It is possible to build digital twins to reduce, simplify and improve development and integration of cameras into complex systems. In this presentation, we will use our recent development to highlight some concrete use cases such as influence of dark current, sensor temperature, colour shift from micro lens array, HDRI Image processing, based on simulated images/video from virtual complex scenes and lighting conditions.

Accurate colour reproducibility of Organic-Photoconductive-Film image sensor and its application
Development of an organic-photoconductive-film (OPF) CMOS image sensor that performs photoelectric conversion with an organic thin film. The OPF image sensor has features including wide dynamic range(WDR), global shutter(GS), tunability of photoelectric conversion wavelength, and low colour mixture due to its unique pixel structure in which organic thin films are stacked over the circuit. In this presentation, we will discuss accurate colour reproducibility of OPF image sensor. The thinning of the photoelectric conversion layer due to the high light absorption rate of the organic thin film suppress colour mixture and achieve high colour reproducibility. This accurate colour reproducibility, WDR, and GS contribute to the construction of robust imaging/sensing systems that do not depend on light source colour temperature, illuminance, or speed.
