Abstract

The normalized efficiencies of transduction of the instantaneous power of optical radiation by a bolometer as a function of the average incident energy per unit length and the nonuniformity of its distribution are determined on the basis of the solution of the heat balance equation averaged over the length of the bolometer when the absorption efficiency factor, the temperature coefficient of resistance, and the specific heat of the material depend linearly on the temperature. Calculations are carried out for platinum bolometers and a radiation wavelength of 10.6 Μm. The amplitude distortions of the recorded signal do not exceed +20%.
