Abstract

A novel design for a compact, light weight, imaging spectrometer has been proposed for an orbiting Lunar mapping mission. Simple in design, its dual arm optical system employs a transmission grating and a dichroic mirror to provide continuous two-octave spectral response. The grating's first order wavelengths are reflected into the SWIR arm, while the second order wavelengths are transmitted to the VNIR arm. The instrument design is that of a push broom camera. It uses one of the detector(s) dimensions for spectral selection, the other detector(s) dimension for cross-track spatial selection, and the forward motion of the platform (in this case, a spacecraft) for down-track spatial coverage.
