Wide-field time-gated SPAD imager for phasor-based FLIM applications

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Andrei Ardelean, Arin Can Ülkü

We describe the performance of a new wide area time-gated single-photon avalanche diode (SPAD) array for phasor-FLIM, exploring the effect of gate length, gate number and signal intensity on the measured lifetime accuracy and precision. We conclude that th ...

Megapixel time-gated SPAD image sensor for 2D and 3D imaging applications

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Andrei Ardelean, Ming-Lo Wu, Arin Can Ülkü, Kazuhiro Morimoto

We present a 1 Mpixel single-photon avalanche diode camera featuring 3.8 ns time gating and 24 kips frame rate, fabricated in 180 nm CMOS image sensor technology. We designed two pixels with a pitch of 9.4 mu m in 7 T and 5.75 T configurations respectively ...

Fluorescence lifetime imaging with a single-photon SPAD array using long overlapping gates: an experimental and theoretical study

Edoardo Charbon, Claudio Bruschini, Andrei Ardelean, Arin Can Ülkü

Developing large arrays of single-photon avalanche diodes (SPADs) with on-chip time-correlated single-photon counting (TCSPC) capabilities continues to be a difficult task due to stringent silicon real estate constraints, high data rates and system complex ...
