Fig. 11From: 16-channel SiPM high-frequency readout with time-over-threshold discrimination for ultrafast time-of-flight applicationsCoincidence multi-photon time resolution of the different SiPM-ASIC channel combinations illuminated with optical photons at 406Â nm and a pulse frequency of 10Â kHz and triggering at different TOFPET2 ASIC thresholds \(\mathsf {vth\_t1}\). Data were acquired using Broadcom NUV-MT SiPMs and a DC connection to the TOFPET2 ASICBack to article page
