摘要

A visible, hyperspectral imager using chromotomography (CT) has been built, with the goal of extending the technology to spatially extended sources with quickly varying (> 10 Hz) features, such as bomb detonations and muzzle flashes. Even with a low dispersion, ~0.7 mradm, direct vision prism with undeviated wavelength near λ = 548 nm, spectral resolution of better than △λ < 10 nm across the λ = 400 - 600 nm band is demonstrated with spatial resolution of better than 0.5 mm. The primary objective of this paper is to show empirically that the spatial and spectral resolution of data obtained by a simple CT instrument is unchanged in projection space and reconstructed object space.
