ASTER TIR subsystem and calibrationViewgraphs are given on the purpose of TIR, major functions, characteristics and design of various components, and calibration. The major functions are to acquire image data on the earth's surface in thermal infrared wavelength band, using mercury cadmium telluride (HgCdTe) detectors; to convert the obtained image data into the digital data to meet the Common Signal Processor (CSP) interface, and output the signals; pointing function in cross-track direction to get the wide swath of 232 km; and to calibrate the whole TIR with the blackbody on orbit, then the amplifier and subsequent transmission units are calibrated electrically.
