METHOD OF PROTECTING OPTOELECTRONIC EQUIPMENT FROM LASER EXPOSURE Russian patent published in 2022 - IPC H04N5/238 H01L31/232 

FIELD: optics.

SUBSTANCE: invention relates to protection of optoelectronic equipment (OEE) from powerful optical radiation. Essence of the method of protecting the OEE from laser action consists in receiving the optical radiation of the OEE, dividing the incident optical radiation into two flows in the energy ratio P₁ = K₃P₂ and P₁ >> P₂, where P₁ is the power of the first flow, P₂ is the power of the second flow, K₃ is the coefficient of proportionality, the delay of the first flow relative to the second flow for a preset time t_preset, measuring the power of the second flow P₂ and determining the power of the first flow as P₁ = K₃P₂, comparing its value P₁ with the threshold value P_thr, processing at P₁ < P_thr of optical radiation of the first OEE stream, overlapping at P₁ ≥ P_thr of the first flow for time t < t_preset and protection of the OEE from destruction by optical radiation.

EFFECT: higher efficiency of protection against optical radiation damage.
