IMAGE BESTReview of Quanta Image Sensors for Ultralow-Light Imaging (IEEE TED June 2022)AMMJENACIONAL

[As mentioned in some recent comments on this blog, the latest (vol. 69 no. 6, June 2022) issue of IEEE Transactions on Electron Devices has many interesting papers related to image sensors. I will post summaries here in the coming days.]

In an invited paper in the June 2022 issue of IEEE TED, Jiaju Ma et al. write:

The quanta image sensor (QIS) is a photon counting image sensor that has been implemented using different electron devices, including impact ionization gain devices, such as the single-photon avalanche detectors (SPADs), and low-capacitance, high conversion-gain devices, such as modified CMOS image sensors (CIS) with deep sub-electron read noise and/or low noise readout signal chains. This article primarily focuses on CIS QIS, but recent progress of both types is addressed. Signal processing progress, such as denoising, critical to improving apparent signal-to-noise ratio, is also reviewed as an enabling co-innovation.
