METHOD OF PROTECTING OPTOELECTRONIC EQUIPMENT FROM LASER EXPOSURE

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 = K3P2and P1 >> P2, where P1is the power of the first flow, P2is the power of the second flow, K3is the coefficient of proportionality, the delay of the first flow relative to the second flow for a preset time tpreset, measuring the power of the second flow P2and determining the power of the first flow as P1 = K3P2, comparing its value P1with the threshold value Pthr, processing at P1 Р2, где Р1- мощность первого потока, Р2- мощность второго потока, К3- коэффициент пропорциональности, задержке первого потока относительно второго потока на заданное время tзад, измерении мощности второго потока Р2и определении мощности первого потока, как Р1=К3Р2, сравнении его значения Р1с пороговым значением Рпор, обработке при Р1
