FIELD: light location, communication systems, optoelectronic measurement equipment. SUBSTANCE: device has forming optics with interference filter, photodetector and amplifier connected in series. Automatic noise gain control is placed between controlled input of amplifier and its output and electron-optical converter is inserted between output of forming optics with interference filter and input of photodetector. EFFECT: reduced threshold sensitivity with realization of potential for reception of short pulses in relatively narrow-band path with achievement of maximum of signal-to-noise ratio. 5 dwg
