photon-counting detector

photon-counting detector

A highly sensitive detecting system with a very high time resolution and very low readout noise. Many photon counters use an image tube or microchannel plate as a first stage to intensify the incident beam of light or other radiation, and a CCD array as the final detector. The earliest version was Boksenberg's IPCS.
