OPTICAL RANGE BEARING FINDER Russian patent published in 2009 - IPC G01S17/00 

FIELD: instrument making.

SUBSTANCE: invention relates to optical hardware and is designed to measure angular coordinates of distant objects. The proposed device comprises a focusing receiving optical system, two polarisers, two beam splitters, absorbing prism, rotation prism, three photo receivers, two amplifiers, two dividers, converter and registering unit. Note that, additionally, the proposed device comprises the second focusing receiving optical system, diaphragm, diaphragm drive, 3^rd beam splitter and ocular lens. Note also here that the 2^nd focusing receiving optical system, diaphragm and 3^rd beam splitter are consecutively arranged on the optical axis ahead of the focusing receiving optical system, while the diaphragm is located in the focal plane of the second focusing receiving optical system. Mind that the ocular lens is arranged on the way of the beam reflected from the 3^rd beam splitter, while the diaphragm drive is linked up with the diaphragm control input.

EFFECT: higher validity of measurements.
