Detection of short light pulses by long inertance PbS and PbSe photodetectors

Abstract

Opportunities of application PbS and PbSe p-s for pulse radiation detection with pulses duration to 10 ns are considered. Expression for threshold stream of such detectors are obtained. Threshold stream estimation for typical values photo electrical characteristics and different light pulses duration are carried out. Frequency characteristics of the quasioptimal filters providing a maximum signal-to-noise ratio are calculated.
