OPTO-LASER SYSTEM FOR SIGHTING AND RANGING OF AIR TARGETS Russian patent published in 1998 - IPC

FIELD: ranging systems, in particular, laser range finders, applicable in opto-laser systems for sighting, ranging and tracking of air targets. SUBSTANCE: system uses a laser radiator with a pumping unit and radiation detector included in optical sighting tracking system and ranging channel, as well as a computer unit. The sighting tracking system has a mirror installed for turning, whose position is determined by a signal generated by the computer unit; the laser radiator uses a unit of radiation modulation at frequencies f₁ and f₂, whose output is connected to the input of the laser radiator pumping unit, and the second optical radiation detector employing an avalanche photodiode, as well as a telescopic objective lens used to reduce the beam divergence. EFFECT: sighting, tracking and ranging of armament of different kinds; target designation to homing heads. 3 cl, 1 dwg
