A telescopic microscope equipped with a quanta image sensor for live-cell bioluminescence imaging. [PDF]
Nat MethodsAbstract Bioluminescence is an attractive alternative to fluorescence for live-cell imaging; however, its low intensity has prevented widespread adoption. Specialized microscopes compensate by sacrificing spatial resolution, field of view and dynamic range—constraints imposed by the highest-sensitivity camera to date: the electron-multiplying

What Does a One-Bit Quanta Image Sensor Offer?
IEEE Transactions on Computational Imaging, 2022 The one-bit quanta image sensor (QIS) is a photon-counting device that captures image intensities using binary bits. Assuming that the analog voltage generated at the floating diffusion of the photodiode follows a Poisson-Gaussian distribution, the sensor produces either a ``1'' if the voltage is above a certain threshold or ``0'' if it is below the ...

Noise Suppressed Image Reconstruction for Quanta Image Sensors Based on Transformer Neural Networks. [PDF]
J ImagingThe photon detection capability of quanta image sensors make them an optimal choice for low-light imaging. To address Possion noise in QIS reconstruction caused by spatio-temporal oversampling characteristic, a deep learning-based noise suppression reconstruction method is proposed in this paper.

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.
