DEVICE FOR SINGLE-POSITION MEASUREMENT OF DIRECTION OF ELECTRO-OPTICAL APPARATUS Russian patent published in 2012 - IPC G01S17/06 

FIELD: physics.

SUBSTANCE: device has the following, connected in series and lying on the path of the received optical radiation: a mixing plate and a photodetector with a shaping optical system. The output of the photodetector is connected to the first input of the signal processing unit of the photodetector, the output of which is the output of the device. The following are connected in series on the path of the reference optical radiation: a heterodyne, a heterodyne signal phase front control unit and a mixing plate. The unit for generating heterodyne signal phase front parameters is connected by its first output to the input of the heterodyne signal phase front control unit, and by the second output to the second input of the photodetector signal processing unit. The optical output of the mixing plate is connected on the heterodyne radiation path to the optical input of a controlled reflecting plate. The third output of the unit for generating heterodyne signal phase front parameters is connected to the input of the reflecting plate control unit, the output of which is connected to the input of the controlled reflecting plate.

EFFECT: measurement of angular coordinates of an active and inactive electro-optical apparatus.
