Chromotomographic Imaging CTI offers advantages in remote sensing by resolving intensity distribution spatially, spectrally, and temporally. The Chromotomography Experiment CTEx at the Air Force Institute of Technology AFIT explores the application of CTI as a space-based observer. Previous work in instrument development has revealed many of the intricacies of component fabrication and how they impact the resolving of image data. The proposed CTEx instrument has as its chromatic dispersion element a direct-vision prism DVP that is made to rotate in order to achieve multiple projection angles. Analysis of previous research established the need for a more accurate characterization of the DVP than has been achieved to date. Research herein presents an investigation into precise characterization of a DVP and a proposed mechanical design of the DVP hardware. The findings of this investigation provide the tools to specify fabrication tolerances for the DVP and advance the research effort.
