SYSTEM OF OBJECT TELEORIENTATION Russian patent published in 2013 - IPC H04B10/00 G01S17/00 

FIELD: radio engineering, communication.

SUBSTANCE: system comprises a laser, a double-coordinate acoustic-optical deflector, comprising the first and second anisotropic acoustic-optical cells turned relative to each othe by 90°, the third anisotropic acoustic-optical cell, a telescope and a measuring channel, made of a polarising light-dividing unit, a telescopic system, two pairs of optical wedges, a position sensitive photodetector, a wave plate λ/2 and an optical splitter. Downstream the double-coordinate acoustic-optical deflector there is a polarising light-dividing unit installed with a roof, consisting of a prism in the form of a parallelogram BS-0 with the following components glued to radiation-deflecting faces - a triangular rectangular prism AR-90 and a prism in the form of a parallelogram BkS-0 with a roof on an inclined face, and downstream the third anisotropic acoustic-optical cell there is an optical splitter with a roof representing a prism in the form of a parallelogram BS-0 with the following components glued to radiation-deflecting faces - a triangular rectangular prism AR-90 and a triangular rectangular prism 9 BkR-180 with a roof on a cathetus. The wave plate is installed on the way of radiation propagation as it is reflected from the roof of the polarising light-dividing unit.

EFFECT: increased stability of system operation.
