Abstract

An imaging FTS would be capable of carrying out many of the programs in the DRM, namely all those which require imaging and/or low spectral resolution wide field/multi-object spectroscopy. We review the DRM science areas, describing the relevance of an imaging FTS. Required instrumental capabilities are then derived from the science goals. Our compact camera and imaging FTS instrument design emphasizes simplicity with a single optical train covering a field 6 X 3 arcmin², with a fixed spatial sampling of 0.03 arcsec/pixel on a 12 k X 6 k detector array.
