Abstract

Basic radiometry theory is introduced and applied to an infrared (IR) test set used to provide a collimated beam irradiance to a missile seeker objective for the purpose of calibration and testing. The test set optical elements consist essentially of a thermal radiation blackbody source used with appropriate apertures and an off-axis paraboloidal mirror. The functional configuration and geometrical relationships of the test set are described which Facilitate obtaining parameters necessary for irradiance computations. A short, simple program written in Basic is provided which may be used to determine on--axis irradiance for a given blackbody temperature, target aperture and spectral band. This paper should be of interest to those engaged in related IR seeker performance testing; however, this work is of course applicable in general for basic IR calibration support systems.
