Images from Bits: Non-Iterative Image Reconstruction for Quanta Image Sensors
Sensors, 2016 A quanta image sensor (QIS) is a class of single-photon imaging devices that measure light intensity using oversampled binary observations. Because of the stochastic nature of the photon arrivals, data acquired by QIS is a massive stream of random binary

Optimal Threshold Design for Quanta Image Sensor [PDF]
IEEE Transactions on Computational Imaging, 2018 Quanta Image Sensor (QIS) is a binary imaging device envisioned to be the next generation image sensor after CCD and CMOS. Equipped with a massive number of single photon detectors, the sensor has a threshold $q$ above which the number of arriving photons will trigger a binary response "1", or "0" otherwise.

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.
