OPTOELECTRONIC TARGET SEARCH AND TRACKING SYSTEM Russian patent published in 2000 - IPC

FIELD: instrument engineering, in particular, optoelectronic instruments designed for search of heat-radiating objects and tracking in combination with a range finder used for provision of target indication and solution of sighting tasks. SUBSTANCE: the device has a movable mirror with angle pick-offs and drives, spectrodividing filter, direction-finding channel producing the error signal between the system optical axis and direction to the target, as well as transmitting and receiving laser channels. Enhanced adaptability to manufacture is attained due to making of each channel in the form of structurally self-contained modules which allows the expansion of system capability making use of the variety of the direction-finding and laser channels, with due account made for the dimensional and weight capabilities of flying vehicles, and provided due to installation of a spectrodividing filter in the direction of motion of optical beam past the receiving movable mirror at an angle to the system optical axis, and a lens-between the spectrodividing filter and prism. Enhanced resolving power is attained due to installation of two correcting lenses and a scanning mirror between them in the direction-finding channel in the direction of motion of optical beam before the spherical mirror. EFFECT: enhanced adaptability to manufacture and resolving power. 3 cl, 2 dwg
