METHOD FOR HIDING OPTICAL-ELECTRONIC EQUIPMENT FROM LASER LOCATION SYSTEMS Russian patent published in 2021 - IPC G02B26/04 

FIELD: optoelectronic engineering.

SUBSTANCE: invention relates to the field of optoelectronic engineering and relates to a method for hiding optoelectronic devices from laser location systems. The method includes measuring the parameters of the received optical radiation, distinguishing by their values the parameters of the spontaneous radiation of the transmitting channel of the laser locating device, preceding the main one, registering the time of receiving the spontaneous radiation t_S and determining the time of arrival t_M of the main radiation of the transmitting channel of the laser locating means. The values of the parameters of spontaneous radiation determine N coordinates of the location of the local zones of reflection from the main reflecting surface of the optoelectronic device. From the N coordinates of the local reflection zones, the coordinates of the central local zone and the coordinates (M=2) of the peripheral adjacent local zones are selected. The coordinates of the selected local reflection zones are recalculated into the coordinates of the installation of (M+1) absorbing screens at the input aperture of the optoelectronic device, the area of the screens is calculated and installed in the time Δt < t_S – t_M at the input aperture of the optoelectronic device.

EFFECT: increasing efficiency of hiding and reducing the energy loss of the useful signal during shielding of the aperture.
