Abstract :
The aim of the work is the substantiation of a calibration method of the thin-wire platinum bolometer of laser radiation pulse energy on wavelength 10.6mum. The method uses well-known table temperature dependencies of the specific resistance and the specific heat capacity of platinum. The temperature dependence of the factor of absorption efficiency is determined by temperature dependencies of the refractive and absorption indexes of bolometer material. The averaged along the bolometer length equation of heat balance with no stationary coefficients and nonuniformity distribution of incident energy is solved
