HELMET TARGET INDICATION SYSTEM Russian patent published in 2001 - IPC

FIELD: optoelectron instrumentation. SUBSTANCE: invention is related to systems in which operator interacts with technical means used to generate angular coordinates of sight line of operator fixed with aid of optoelectron devices whose signals provide for automatic sighting of weapon on target. Proposed helmet target indication system includes indication unit made fast to radiators optically coupled to optical-location units each having diaphragm and strip of photosensitive elements and information processing unit. Optical axes of optical-location units and strip of photosensitive elements are placed in one plane and at angles with regard to each other. Each optical-location unit is fitted with objective lens coming in the form of two semi-cylinder lenses linked with flat surfaces, one of them carrying slit diaphragm whose longitudinal axis is parallel to element of cylinder and is perpendicular to plane of position of photosensitive strips. Interference filter is put on second flat surface of semi-cylinder lenses. Optical- location units are located in common case. EFFECT: enhanced accuracy characteristics of video signal and quick response of system. 3 cl, 3 dwg
