Airborne Visible/Infrared Imaging Spectrometer (Aviris) Spectrometer Design And Performance

Abstract

The development of the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) has been completed at the Jet Propulsion Laboratory, California Institute of Technology. This paper outlines the functional requirements for the spectrometer optics subsystem, and describes the spectrometer optical design. The optical subsystem performance is shown in terms of spectral modulation transfer functions, radial energy distributions and system transmission at selected wavelengths for the four spectrometers. An outline of the spectrometer alignment is included.
