Abstract
Abstract : This document describes the auxiliary equipment used to adapt the Aerospace Near-Infrared Imaging Spectrograph (NIRIS) for remote sensing and the specific configuration used for launch observations at Vandenberg AFB. This equipment enables NIRIS's considerable capability for hyperspectral imaging and absolute spectrophotometry (including instantaneous wavelength coverage from 0.8-2.5 micrometers at spectral resolutions from 56-1200) to be applied to a number of remote sensing observations, but most specifically the spatially resolved spectroscopy of rocket plumes. Equipment includes a small telescope that provides a 9 degrees field of view in the spatial dimension (along the slit), digital cameras for both slit viewing and direct imaging of the field, a fast shutter and filterwheel outfitted with neutral density filters for brightness control and saturation avoidance, and an electrically isolating interface plate that allows mounting the entire 400+ lb pack- age to a large alt-azimuth tracking mount.
