On-Chip Compressive Sensing with a Single-Photon Avalanche Diode Array
Sensors, 2023 Single-photon avalanche diodes (SPADs) are novel image sensors that record photons at extremely high sensitivity. To reduce both the required sensor area for readout circuits and the data throughput for SPAD array, in this paper, we propose a snapshot ...

A 72 × 60 Angle-Sensitive SPAD Imaging Array for Lens-less FLIM
Sensors, 2016 We present a 72 × 60, angle-sensitive single photon avalanche diode (A-SPAD) array for lens-less 3D fluorescence lifetime imaging. An A-SPAD pixel consists of (1) a SPAD to provide precise photon arrival time where a time-resolved operation is utilized ...

SPAD array chips with full frame readout for crystal characterization. [PDF]
EJNMMI Phys, 2015 We present single photon sensitive 2D camera chips containing 88x88 avalanche photo diodes which can be read out in full frame mode with up to 400.000 frames per second. The sensors have an imaging area of ~5mm x 5mm covered by square pixels of ~56µm x 56µm with a ~55% fill factor in the latest chip generation. The chips contain a self triggering logic
