METHOD FOR PROTECTING OPTICAL-ELECTRONIC MEANS FROM POWERFUL LASER COMPLEXES Russian patent published in 2021 - IPC G01S7/00 

FIELD: radio engineering

SUBSTANCE: invention relates to radio engineering and can be used for protecting optical-electronic means from powerful optical radiation. To achieve a technical result, optical radiation is received by an optical-electronic means, optical radiation is received by an optical-electronic means via an additional lens which is installed in the plane of the optical-electronic means location at a distance from the main lens of the optical-electronic means R≥R_min where R≥R_min is the minimum value of the radius of the zone relative to the location of the main lens of the optical-electronic means, beyond which the influx of heavy laser radiation will not affect the optical-electronic means at a specified distance of deflection, the location radiation of a powerful laser complex is received via an additional lens by the optical-electronic means and the parameters thereof are measured, the moment when the optical-electronic means is exposed to powerful laser radiation by a powerful laser complex is determined by the parameters of location radiation of a powerful laser complex and at the time of the exposure of the optical-electronic means to a powerful laser radiation of a powerful laser complex the optical radiation of the optical-electronic means is received via the main lens.

EFFECT: improved quality of protection of optical-electronic means.
