Infrared Standards to Improve Chamber 7V Beam Irradiance Calibrations
Abstract
A working standard, low-temperature, blackbody has been developed for use in establishing radiometric calibrations that are directly traceable to the National Bureau of Standards. The blackbody will be used in the process of establishing a calibration of the 7V beam irradiance, as required for LWIR sensor testing. The 7V beam irradiance calibration process is reviewed to indicate the manner in which the working standard blackbody fits into the overall calibration scheme. A complete description of the design and calibration of the working standard blackbody is presented. The device is utilized to calibrate a phosphorous-doped, silicon bolometer and the bolometer calibration procedure and results are also presented. In the overall 7V beam irradiance calibration process, the bolometer will be used to calibrate the operational sources that are utilized in 7V sensor test installations.
