Abstract
To extract useful information for imaging spectroscopy measurements the data must be calibrated with respect to their spectral, radiometric, spatial and uniformity characteristic. Since the late 1970s JPL has be involved in developing imaging spectrometer instruments to pursue science objectives on Earth and well as other bodies in the solar system. Over this time period, with the advance of technology, the trend in these instruments has been toward increasing measurement quality in terms of uniformity, signal-to-noise ratio and calibration. The ASD full-range spectrometer has play an important role in laboratory calibration as a transfer spectrometer and independent check calibration source properties. This field spectrometer is also used extensively in-flight calibration validation experiments for Earth imaging spectrometers. We report the use of the ASD spectrometer in the calibration activities of AVIRIS and the Moon Mineralogy Mapper high uniformity and high signal-to-noise ratio imaging spectrometers.
