A field deployable hyperspectral imager utilizing chromotomography
(CT), with a direct vision prism (DVP) as the dispersive element,
has been constructed at AFIT. This research is focused on the
construction and characterization of a CT imager as prototype for a
follow on International Space Station based instrument. The
instrument is currently the fastest known direct vision prism
hyperspectral CT imager. The imager was capable of acquiring
spectral data for a transient event lasting less than 0.12 s. The
ability to identify potassium, sodium, and absorption features from
the instrument's acquired data shows the potential this imager
possess. This research has shown that the instrument has the
ability to capture data of static scenes, and more importantly, the
imager acquired spectral data for rapidly evolving scenes. Because
CT imaging has the potential ability to capture spatial and
spectral data from transient events, a space-based system may
enhance current capabilities of identifying, classifying, and
characterizing battlespace events such as artillery/AAA muzzle
flashes, detonations, and missile launches.
