SURVEILLANCE DEVICE-SIGHT WITH DEVICE FOR INPUT OF RANGE UNIT MARK Russian patent published in 2018 - IPC G02B23/12 F41G3/06 

FIELD: military equipment.

SUBSTANCE: surveillance device – sight with an input device for a range unit mark contains a head part consisting of protective glasses and two prism cubes, and three vertically arranged channels: single optical channel combined with a receiving channel of a pulsed laser range unit, radiating channel of a pulsed laser range unit and multiple optical-electronic channel with two interchangeable modes of operation. Range unit mark is introduced into the field of view of a multiple optical-electronic channel by applying an electron-optical converter (EOC) onto a photocathode or screen, and in the optical mode, the range unit mark of a similar configuration is applied to the grid built into the conjugation optics, replacing the EOC when switching to the optical mode.

EFFECT: technical result – ensuring the accuracy of measuring the distance to the target without correcting the direction of the axis of the radiating channel of the range unit when calibrating the product in the application object.
