METHOD OF PROTECTING OPTOELECTRONIC EQUIPMENT FROM LASER SYSTEMS USING FALSE OPTICAL TARGETS Russian patent published in 2024 - IPC G01S7/48 G01S17/02 G02B26/00 

FIELD: physics.

SUBSTANCE: invention relates to protection of optoelectronic equipment (OEE) from powerful laser radiation. Disclosed method consists in the following. Using K+M of movable false optical targets (FOT) relative to the simulated OEE. Using the a priori data on the parameters of the laser exposure complex, the specified parameters of the OEE and the current parameters of the meteorological environment in the area of application of the laser exposure complex and the OEE, calculating the current minimum value of the FOT installation distance R_NP(L) relative to the OEE, beyond which the flow of the incident powerful laser radiation of the laser action complex will not hit the OEE when the laser action complex damaging channel is guided to the FOT at the current range L of using the laser action complex on the OEE, and the current minimum value of the FOT installation distance R_P(L) relative to the OEE, beyond which the laser locator of the laser action complex resolves the OEE and the FOT as separate targets at the current range L of using the laser action complex on the OEE. If R_p(L) < R_NP(L), then m-th FOT is moved at distance from OEE, equal to R_p(L), if R_p(L) > R_NP(L), then the m-th FOT is moved at a distance from the OEE, which is equal to R_NP(L), and the k-th FOT is moved at a distance from the OEE, which is equal to At the same time, when moving K+M numbers the FOT provide distances R≥RP(L) between k-th and k+1-th, between m-th and m+1-th, between m-th and k-th FOT,

EFFECT: increased efficiency of OEE protection against damage by optical radiation using FOT.
