Dark count rateとは
WebDark Count Rate: This is the average rate of registered counts in the absence of any incident light and determines the minimum count rate at which the signal is dominantly … The resulting average number of counts per second is called dark count rate (DCR) and is the key parameter in defining the detector noise. It is worth noting that the reciprocal of the dark count rate defines the mean time that the SPAD remains biased above breakdown before being triggered by an undesired … See more A single-photon avalanche diode (SPAD) is a solid-state photodetector within the same family as photodiodes and avalanche photodiodes (APDs), while also being fundamentally linked with basic diode behaviours. As with … See more Structures SPADs are semiconductor devices based on a p–n junction reverse-biased at an operating voltage … See more The history and development of SPADs and APDs shares a number of important points with the development of solid-state technologies such … See more • Avalanche photodiode (APD) • p–n junction • Silicon photomultiplier (SiPM) • Oversampled binary image sensor See more Since the 1970s, the applications of SPADs have increased significantly. Recent examples of their use include lidars, time of flight (ToF) 3D imaging, PET scanning, single-photon experimentation within physics, fluorescence lifetime microscopy and … See more While both APDs and SPADs are semiconductor p-n junctions that are heavily reverse biased, the principle difference in their properties is derived from their different biasing points upon the reverse I-V characteristic, i.e. the reverse voltage applied to … See more
