Paper Abstract

We report results from a field demonstration of a non-scanning high-speed imaging spectrometer capable of simultaneously recording spatial and spectral information about a rapidly changing scene. High-speed spectral imaging was demonstrated by collecting spectral an spatial snapshots of a missile in flight. This instrument is based on computed-tomography concepts and operates in the visible (420 - 740 nm). Raw image data were recorded at video frame rate (30 fps) and an integration time of 2 msec. Reconstructions of the spatial and spectral scene information from the raw image data take considerably longer, on the order of 30 seconds. Comparisons of reconstructed spectra with spectra acquired by a non- imaging reference spectrometer have shown that extended-source spectra were reconstructed accurately. We present representative missile spectral-signature data and missile- tracking linear-classifier results from the missile firing.
