METHOD AND DEVICE OF AZIMUTH-ELEVATION INDICATION IN OPTICAL-LOCATION SYSTEMS Russian patent published in 2017 - IPC G01S17/89 G02B26/10 

FIELD: physics.

SUBSTANCE: method of azimuth-elevation indication in optical-location systems contains the formation of a combined optical beam from the probing and reference laser radiation, the direction of the probing and control laser beams, the separation and summation of the probing and reflected laser beam from the object and the reference beam. In this case, the probing beam is diaphragmed by the radial-slit diaphragm of the probing mirror. The formation of a shadow mark in the probing beam and a light mark passing through the radial-slit diaphragm is performed. The light mark is projected onto the surface of the limb.

EFFECT: providing a direct visual indication of the probing radiation direction along the azimuth and elevation angle.
