Thermal Infrared Multispectral Scanner
NASA Stennis Space Center, the Jet Propulsion Laboratory (JPL) and Daedalus Corporation have developed the Thermal Infrared Multispectral Scanner (TIMS) for exploiting mineral signature information. The TIMS is a Daedalus multispectral scanning system using a dispersive grating and a six element mercury cadmium telluride detector array to produce six discrete channels in the 8.2 to 12.2 micron region. Used as an airborne geologic remote sensing tool, the TIMS acquires mineral signature data that permits the discrimination of silicate, carbonate and hydrothermally altered rocks. TIMS data have been used extensively in volcanology research in the western United States, Hawaiian islands and Europe. The wavelength bands sampled are:
||8.2 - 8.6
||8.6 - 9.0
||9.0 - 9.4
||9.4 - 10.2
||10.2 - 11.2
||11.2 - 12.2
