METHOD FOR PROTECTING OPTICAL-ELECTRONIC EQUIPMENT OF AIRCRAFT FROM IMPACT OF POWERFUL LASER RADIATION Russian patent published in 2021 - IPC H04N5/238 H01L31/232 G01B5/00 

FIELD: optoelectronic devices.

SUBSTANCE: invention relates to the field of protection of optoelectronic devices (OED) from powerful optical radiation. The essence of the invention: the method of protecting the OED of aircraft (AC) from the impact of powerful laser radiation consists in detecting and measuring the parameters of the signals of the locating module (LLM) of the powerful laser device (PLD), determining the values of the parameters of the signals of the PLD LLM and the current values of the coordinates of the location of the OED of the aircraft, coordinates of the location of the PLD, determination of the values of the measured parameters of the signals of the laser LLM of the PLD of the PLD class and its typical parameters of the signals of the power laser module (PLM), the calculation using the values of the typical parameters of the signals of the PLD PLM, the values of the measured coordinates of the location of the PLM, the values of the current coordinates of the location of the OED of the aircraft, the values given spatial parameters of the generated local aerosol formation (LAF), the values of the specified parameters of the energy attenuation of the PLD PLM signals by the LAF formed, the values of the specified threshold power level of optical signals at the input of the aircraft OED, at which the OED of the aircraft retains its working capacity, the values of the required coordinates of the formation of the LAF, the formation in the required coordinates from the time of detection of the signals of the LLM of the PLD during the time Δt_LAF of the LAF and the protection of the OED LAF of the aircraft from the influence of the signals of the PLD PLM, with Δt_LAF <Δt, where Δt is the time between the moments of emission of signals from LLM and PLD PLM, by changing the position of the aircraft and the orientation of the field of view of the OES of the aircraft from the field of view of the OED of the LAF and maintaining the view of a given area of the underlying surface.

EFFECT: improving the efficiency of protecting the OED from damage by optical radiation.
