Abstract
The design and flight results of a multimode satellite instrument are described. The prime mission is to produce imagery of the earth’s auroral activity with a selectable 30-Å spectral window in the vacuum ultraviolet spectrum ranging from ~1100 to 1900 Å. This instrument, known as AIM (auroral/ionospheric mapper), also functions as a photometer operable at preselected wavelengths with the same spectral window or as a spectrometer scanning the full spectral range. As a part of the AIM sensor there are two fixed wavelength photometers, one at 3914 Å and the other at 6300 Å, each with a 10-Å spectral window. The mechanical, optical, photometric, and electrical design criteria and selections are presented.
