Author Affiliations +
We have developed a large-size gold-coated integrating sphere with an inner diameter of 1 m for use as a spectral radiance calibration standard in the short-wave infrared (SWIR) range. We anticipate that this integrating sphere will be used for the radiometric calibration of space-borne sensors such as SGLI (second-generation global imager) and HISUI (hyperspectal imager suite) prior to their launch. In this paper, we show the initial results of performance evaluation testing of the gold-coated integrating sphere system.
