Paper Abstract

Infrared Multispectral Linear Array (MLA) pushbroom scanners are being developed for NASA's Advanced Land Observing System (ALOS) for the late 1980's to mid 1990's. Pushbroom scanners offer high spectral, spatial and temporal resolution, and high reliability through design simplicity. They use integral chopping and calibration. They require no moving optics. They are lighter, simpler and more compact than their electro-mechanical predecessors. Infrared hybrid focal planes under development for MLA instruments require less power and less space radiative cooling per channel than current LANDSAT sensors. It is anticipated that pushbroom's increased signal integration time across a ground element will provide greater sensitivity and discrimination of the earth's resources. For all of these reasons NASA has selected pushbroom scanners for future ALOS missions.
