IDTechEx Discusses Expanding Machine Vision to Accelerate Adoption of Emerging Image Sensor Technologies
BOSTON, June 15, 2021 /PRNewswire/ — Image sensing is a critical capability, used in multiple applications ranging from webcams and smartphone cameras to autonomous vehicles and industrial inspection. IDTechEx’s brand new report, “Emerging Image Sensor Technologies 2021-2031: Applications and Markets“, explores the emerging image sensor market in depth, covering a diverse range of technologies from flexible thin-film photodetectors to event-based vision.
Motivation for emerging image sensor technologies
While conventional CMOS detectors for visible light are well established and somewhat commoditized, at least for low value applications, there is considerable opportunity for more complex image sensing hardware that offers capabilities beyond the simple acquisition of red, green and blue (RGB) intensity values. at each pixel. This is largely due to the growing adoption of computer vision, in which image analysis is performed by computational algorithms. Machine learning requires as much input data as possible to establish correlations that can help identify and classify objects. Therefore, the acquisition of optical information over different wavelength ranges or with spectral resolution, for example, is very advantageous.
Of course, emerging image sensor technologies offer many other benefits. This may include similar capabilities at lower cost, increased dynamic range, improved temporal resolution, spatially variable sensitivity, high resolution global shutters, reducing unwanted influence of scattering, flexibility/compliance, etc.
The brand new IDTechEx report, “Emerging Image Sensor Technologies 2021-2031: Applications and Markets“, covers many emerging technologies, in particular:
- Quantum dots on hybrid silicon image sensors
- Organic photodetectors on silicon hybrid image sensors
- Emerging SWIR image sensor technologies, including extended range silicon.
- Organic photodiodes and perovskites (OPDs and PPDs)
- Event vision
- Hyperspectral imaging
- Flexible X-ray image sensors
- Wavefront Imaging
Emerging Image Sensor Technologies
Emerging image sensor technologies in the report include:
Hybrid image sensors – Adding an additional light-absorbing layer above a CMOS readout circuit is a hybrid approach that uses organic semiconductors or quantum dots to increase spectral sensitivity in the SWIR region. Currently dominated by expensive InGaAs sensors, this new technology promises a substantial price reduction and thus the adoption of SWIR imaging for new applications such as autonomous vehicles.
Extended Range Silicon – Given the very high price of InGaAs sensors, there is considerable motivation to develop much cheaper alternatives that can detect light towards the lower end of the SWIR spectral region. Such SWIR sensors could then be used in vehicles to provide better vision through fog and dust through reduced scattering.
Thin-film photodetectors – Detecting light over a large area, rather than at a single small detector, is highly desirable for biometric data acquisition and, if flexible, for imaging through the skin. Emerging approaches that use solution-processable semiconductors offer a compelling way to produce large-area compliant photodetectors for applications such as under-display fingerprint detection.
Event vision – Autonomous vehicles, drones, and high-speed industrial applications require image sensing with high temporal resolution. However, with conventional frame-based imaging, high temporal resolution produces large amounts of data that require computationally intensive processing. Event-based vision is a new way of obtaining optical information that combines greater temporal resolution of rapidly changing image regions with much reduced data transfer and subsequent processing requirements.
In summary, the growing adoption of computer vision provides an excellent opportunity for emerging image sensing technologies that offer capabilities beyond conventional CMOS sensors. This report offers a comprehensive overview of the emerging image sensor technologies market, covering a multitude of applications ranging from autonomous vehicles to industrial quality control.
