PULSED OPTICAL SIGNAL RECEIVER Russian patent published in 2014 - IPC G01J1/44 

FIELD: physics.

SUBSTANCE: invention relates to equipment of receiving pulsed optical radiation, primarily to receivers of pulsed laser range finders and similar devices for measuring time intervals between optical pulses. The pulsed optical signal receiver has a photodetector with a bias source and a load connected to an amplifier; the amplifier is in form of two transistor repeaters with a common load; the input of one of the repeaters is connected to the load of the photodetector, and the input of the second repeater is configured to be connected to an external signal source, wherein the inputs of the transistor repeaters are connected in parallel to switches which are connected to a commutator switch which controls their closing and opening in anti-phase.

EFFECT: high accuracy of timing a received signal and, consequently, high accuracy of measurement using devices employing such a receiver.
