Hyperspectral imager characterization and calibration

Current radiometric calibration standards, specifically blackbody and lamp-based optical radiation sources, produce spatially, spectrally, and temporally simple scenes. Hyperspectral imaging instruments, which in-practice view spatially, spectrally, and temporally complex scenes, would benefit from advanced radiometric artifacts that more closely resemble scenes the sensor will ultimately view. Techniques and artifacts that advance sensor characterization and algorithms that reduce the impact of scattered light on sensor performance are presented in this work. Example applications of the new technologies and algorithms on remote sensing hyperspectral imaging instruments are presented.
