Effect of the Transition Points Mismatch on Quanta Image Sensors [PDF]
Sensors, 2018 Mathematical models and imaging models that show the relationship between the transition points mismatch of analog-to-digital converters (ADCs) and the bit error rate (BER) in single-bit and multi-bit quanta image sensors (QISs) are established.

Imaging Cherenkov photon emissions in radiotherapy with a Geiger-mode gated quanta image sensor. [PDF]
Opt Lett, 2019 The emission of Cherenkov photons from human and animal tissue can be observed during clinical x-ray or particle beam irradiation. However, imaging this weak emission with the necessary single-photon sensitivity in the clinical room is challenging because of milliwatt-level ambient room lighting and the presence of stray high-energy radiation.

HDR Imaging With Quanta Image Sensors: Theoretical Limits and Optimal Reconstruction [PDF]
IEEE Transactions on Computational Imaging, 2020 High dynamic range (HDR) imaging is one of the biggest achievements in modern photography. Traditional solutions to HDR imaging are designed for and applied to CMOS image sensors (CIS). However, the mainstream one-micron CIS cameras today generally have a high read noise and low frame-rate.

Color Filter Arrays for Quanta Image Sensors
IEEE Transactions on Computational Imaging, 2020 Quanta image sensor (QIS) is envisioned to be the next generation image sensor after CCD and CMOS. In this paper, we discuss how to design color filter arrays for QIS and other small pixels. Designing color filter arrays for small pixels is challenging because maximizing the light efficiency while suppressing aliasing and crosstalk are conflicting ...

Megapixel photon-counting color imaging using quanta image sensor
Optics Express, 2019 Quanta Image Sensor (QIS) is a single-photon detector designed for extremely low light imaging conditions. Majority of the existing QIS prototypes are monochrome based on single-photon avalanche diodes (SPAD). Passive color imaging has not been demonstrated with single-photon detectors due to the intrinsic difficulty of shrinking the pixel size and ...
