METHOD FOR ADJUSTMENT OF LASER SYSTEM RADIATOR OF GUIDANCE SIGHT-INSTRUMENT Russian patent published in 2000 - IPC

FIELD: rocketry, in particular, guided missile complexes. SUBSTANCE: radiation of additional radar 1 is directed to the radiator optical axis of the radiator of laser system 2 through the lenses of condenser 3, reflected up to spot registration, then registered laser radiation is directed to modulator 6, and a control field of zoom lens 7 is formed with programmed motion of movable components. Additional radiator 1 is installed perpendicularly to the radiator axis of laser system 2, beams are registered in the point of intersection with the tautochronic optical path, condensers 3, 5 form a magnified image of radiating p-n junctions of lasers 1,2, which is transformed to a linearly polarized beam in the form of narrow strips in the horizontal and vertical planes. The lasers are cut in alternately, and a reflecting surface with polarizing coating is installed near the point of intersection of beams, which, passing-through radiation of the radiator of laser system 2 and reflecting radiation of additional laser 1, forms radiation in the form of a cross, which is directed to modulator 6 and zoom lens 7 to form the control field. EFFECT: enhanced power output of laser beam of guidance sight- instrument, reduced mass and overall dimensions of it, reduced labour content at assembly and adjustment, fine registration of beams of two lasers and stable direction of them in all operating conditions. 2 dwg
