摘要：

We report results from a demonstration of a midwave-infrared, nonscanning, high-speed imaging spectrometer capable of simultaneously recording spatial and spectral data from a rapidly varying target scene. We demonstrated high-speed spectral imaging by collecting spectral and spatial snapshots of blackbody targets and combustion products. The instrument is based on computed tomography concepts and operates in a midwave-infrared band of 3.0-5.0 mum. We record raw images at a frame rate of 60 frames/s, using a 512 X 512 InSb focal-plane array. Reconstructed object cube estimates were sampled at 46 X 46 X 21 (x, y, lambda) elements, or 0.1-mum spectral sampling. Reconstructions of several objects are presented.
