Abstract
The newly emerging field of imaging spectrometry is driving the interest for remote sensing instruments that image the Earth's surface in contiguous spectral bands. The High Resolution Imaging Spectrometer (HIRIS) is a facility instrument for "Mission to Planet Earth" and will be flown on the first of NASA's Earth Observing System (EOS) platforms. HIRIS is a pointable instrument and images the surface of the Earth with 30 m nominal spatial sampling. The instrument disperses light by use of prisms to obtain 10 nm nominal spectral sampling from 0.4 mm to 2.45 mm. The instrument requirements are discussed. The baseline optical design and the trade-offs made in arriving at that design are presented. This publication was prepared by the Jet Propulsion Laboratory, California Institute of Technology, under contract with NASA.
