1. Measuring method of impulse energy of optical radiation which consists in irradiation of pyroelectric detector by impulse. filtration and amplification of electric signal, which after that come into analog-digital convertor (ADC), the following transmission of digital pattern of signal into computer with the next mathematical treatment which consists of determination of zero level by part of digital pattern of signal which precedes to impulse beginning, extracting of the drop area of signal after its extremum, its extrapolation and calculation of impulse energy which differs in that the electrical signals that correspond to radiation impulses of different forms and lengths are transformed into electrical impulses of similar form and length, the marked area is approximated by straight line and moment of impulse radiation beginning is calculated by formula tH=t0
