Multispectral Scanner MSS

(1) A non-photographic imaging system, which utilizes an oscillating mirror and Fiber optic sensor array. The mirror sweeps from side to side, transmitting incoming Energy to a Detector array which sequentially outputs brightness values (that is, signal strengths) for successive pixels one swath at a time. The forward motion of the sensor Platform carries the instrument to a position along its path where an adjacent swath can be imaged (2) For Landsats 1,2,3, 4, and 5 the multispectral Scanner sensed Radiation simultaneously by an array of six detectors in each of four spectral bands from 0.5 to 1.1
