OPTICAL SIGHT WITH TRACKING RANGE FINDER Russian patent published in 2011 - IPC F41G7/26 G01C3/08 

FIELD: weapons and ammunition.

SUBSTANCE: proposed sight may be used in controlled weapons guidance systems. It comprises opto-electronic unit accommodating finder channel video transducer and range finder channel, guidance and stabilisation drive, control signal conversion unit, target tracking automatic device, transducers of control signals from drives and aforesaid automatic device, and monitor. Additionally, sight comprises scaling unit, acoustic-optical deflector electronic control unit including thermal compensation unit, adder, two-channel frequency synthesizer, and two-coordinate acoustic-optical deflector arranged between laser radiator and output optical system of range finder channel transmitter. Diametre d of range finder photo receiver LED sensitive sire satisfies the condition d≥2F·φ_m, where F is focal distance of range finder receiving optical system; φ_m is maximum angular error of target tracking by optical sight.

EFFECT: accurate range finding for flying high-speed maneuvering targets thanks to target tracking error compensation in rage finder channel.
