METHOD OF ACCOUNTING FOR INSTABILITY EFFECT OF LASER RADIATION WHEN REPRODUCING AND TRANSMITTING POWER UNIT Russian patent published in 2015 - IPC G01J5/50 G01J5/00 G01M11/02 

FIELD: physics.

SUBSTANCE: method includes taking measurements using two measurement transducers, the time constants of which differ by not less than two orders; based on output signals of the transducers, determining pulse functions of the measurement transducers and calculating the convolution of the signal from the measurement transducer with a low time constant with the pulse function of the measurement transducer with a higher time constant; calculating the coefficient of proportionality between the function of the measurement transducer with a higher time constant and the convolution result. The transfer constant of the average power unit is the calculated coefficient of proportionality.

EFFECT: high measurement accuracy in unstable laser radiation conditions.
