OPTICAL PULSE RECEIVER Russian patent published in 2019 - IPC G01J1/04 G02B26/02 H01L31/232 

FIELD: optics.

SUBSTANCE: invention relates to reception of optical radiation and to a receiver of optical pulses. Receiver includes a photosensitive element, a signal processing circuit and an optical gate mounted in front of the photosensitive element. Optical gate is made in the form of a shutter with two working positions. Device comprises a shutter drive including a yoke, a middle part of which is hingedly fixed on the body of the receiver, a elastic element and two parallel stretch marks in the swing plane of the yoke. First stretching is fixed between one lever of the yoke and the body, and the second stretching is fixed between the second arm of the yoke and an elastic element, the other end of which is fixed on the body. Shutter is installed at the connection point of the second tensioner with an elastic element. Elastic element is in a stressed state, and tensioners are electrically in-series connected to each other conductive threads, to ends of which external source of control electric signal is connected.

EFFECT: providing operability of the device under active and passive laser countermeasures with minimum dimensions and maximum sensitivity at low level of signals.
