STAND FOR MEASURING THE DIRECTION FINDING CHARACTERISTIC OF LASER ILLUMINATION DETECTION DEVICE Russian patent published in 2023 - IPC G01S3/78 

FIELD: testing optoelectronic devices.

SUBSTANCE: testing optoelectronic devices in non-stationary conditions. Invention relates specifically to measurement of direction-finding characteristics of equipment for detecting laser illumination of mobile objects of ground military equipment, equipped with a rotary turret artillery installation. A variant of rational placement on a stand designed to measure the direction-finding characteristics of laser illumination detection equipment as part of a mobile ground-based object of military equipment, used external equipment - a source of laser radiation and a diffuse reflector (shield), optically connecting this source and the input part of the receiving heads of the equipment, is proposed. The receiving heads of the equipment are illuminated by scattered radiation from a diffuse reflector when it is installed in close proximity to the object and an external source of radiation. A divergent light flux is formed from the reflector, the dimensions of the solid angle of which, depending on the angular divergence of the laser source beam and the scattered properties of the reflector, form an extended irradiation zone on the tower of the object, sufficient to overlap the input windows of the heads located along the perimeter of the tower.

EFFECT: increasing the efficiency of measuring the direction-finding characteristics of the equipment in factory or field conditions and simplifying the process of preparing for these measurements.
