Frontiers in Physics, 2022 The ability to detect single photons is becoming an enabling key capability in an increasing number of fields. Indeed, its scope is not limited to applications that specifically rely on single photons, such as quantum imaging, but extends to applications where a low signal is overwhelmed by background light, such as laser ranging, or in which faint ...

On the time gating of SPADs in a synchronized time-gated SPAD array in Raman spectroscopy [PDF]
2017 IEEE SENSORS, 2017 The effect of the timing of the biasing of a single photon avalanche diode (SPAD) on the accuracy of a time-gated SPAD array has been studied in this work. The measurement was realized in a time-gated Raman spectrometer utilizing a 16×256 CMOS SPAD array with on-chip time gating electronics.
