LASER SYSTEM OF THE OBJECT TELEORIENTATION Russian patent published in 2017 - IPC G01S17/02 H01S3/10 

FIELD: physics.

SUBSTANCE: system consists of a sequentially installed laser, a two-coordinate acoustooptical deflector, a laser polarisation plane control unit, a polarisation beam-splitting prism array, and a telescope. The acoustooptical deflector includes two anisotropic acousto-optical cells, deployed relative to each other by 90°. The polarised beam-splitting block consists of a prism in the form of a parallelogram SB-0 and the faces of the rectangular prism AP-90 and a rectangular prism BKR-180 with the roof on the leg attached to it. Reflecting faces of the prism SB-0 have polarisation-selective reflective coatings with a high reflection coefficient for the plane of polarisation of laser radiation, the electric vector of which is parallel to the plane of the reflecting faces.

EFFECT: reduction of dimensions and increase in system reliability.
