LASER INFRA-RED SIGHT Russian patent published in 1998 - IPC

FIELD: optical sights, applicable as an indicating device for fine localization of remote optoelectronic target, as well as a device for aiming of laser radiation on it. SUBSTANCE: a position-sensitive device in the form of an optoelectronic transducer is used with a narrow band interference filter with a bandwidth equal to the width of the spectrum of the infra-red semiconductor laser, and a mirror with a dielectric coating reflecting high- power laser radiation is installed between the objective lens of the position-sensitive device and interference filter. An N-channel periscope scanner is installed at the outlet of the objective lens of the position- sensitive device, the distance between the channel outlets: $$$, and the distance between the optical axes of the objective lens of the infra-red semiconductor laser and of the objective lens of the position-sensitive device $$$, where Q-angle of the field of vision of the optoelectronic target; l-distance between the scanner and the optoelectronic target; D-diameter of the optoelectronic target objective lens; $$$ - wavelength of the infra-red semiconductor laser. EFFECT: enhanced efficiency of aiming.
