Radiance calibration of target projectors for infrared testing

This paper provides a procedure for radiometric calibration of infrared target projectors using the RAD-9000 MWIR/LWIR spectral radiometer - a high-performance instrument supporting extremely accurate absolute and relative radiometric calibration of EO test systems. We describe the rationale for radiometric calibration, an analysis of error sources typically encountered by investigators during calibration of infrared imaging cameras when using target projectors, and a strategy for performing an absolute system end-to-end radiometric calibration with emphasis on high accuracy and ease of use.
