Studies were conducted to determine the optical absorption characteristics of various paints and coatings used on Army systems. The method used to determine the temperature-dependent effective absorptance consisted of heating a painted sample with a thermal light source and analyzing the rate of the increase in temperature. This report presents the derivation of equations required to determine the effective absorptance and the experimental procedures involved in obtaining the time-dependent temperatures of the samples.
