OPTICAL SIGHT OF GUIDED PROJECTILE GUIDANCE SYSTEM Russian patent published in 2000 - IPC

FIELD: optical systems of guided projectile guidance, applicable in guided weapon systems with teleorientation in the laser beam. SUBSTANCE: the optical sight uses a non-transparent blind installed on the rotary prism cell, two optoelectronic sensors, two delay circuits and a pulse shaper. The blind is made in the form of a non- transparent sector with a turn angle of 180 deg, whose sides pass through the axis of prism rotation and are turned relative to the plane of inclination of the prism faces through angle α in the direction of rotation of the scanner, and the sector radius provides for overlapping of the optical axes of the optoelectronic sensors fixed in parallel with one of the measured co-ordinates. In the plane perpendicular to the projector optical axis the angle between the lines connecting each sensor to the prism axis of rotation makes up 90 deg, the outputs of the first and second optoelectronic sensors are connected to the first and second inputs of the pulse shaper, respectively, whose first and second outputs are connected to the inputs of the first and second lasers, respectively, and the delay circuits can control the delay time within 0 to Tα/π, where T - period of prism rotation, α - angle between the plane of inclination of prism faces and the side of the non-transparent sector. EFFECT: enhanced accuracy of coding of co-ordinates at formation of optical field. 2 cl, 4 dwg, 2 tbl
