CTIS Demonstration at White Sands Missile Range

This report reviews the progress on a demonstration of visible and Mid-Wave Infrared MWIR imaging spectrometers at a White Sands Missile Range WSMR launch. These instruments are non-scanning high speed imaging spectrometer capable of simultaneously recording spatial and spectral data from a rapidly varying target scene. High-speed spectral imaging was demonstrated by collecting spectral and spatial snapshots of a missile intercept at WSMR. The instruments are based on computed tomography concepts. The infrared instrument operates in a 3.0 to 4.6 micrometers. Raw images were recorded at a video frame rate of 30 fps using a 160 x 120 InSb focal plane array. A reconstruction of a simple 819 K blackbody object is presented as proof of concept. A visible spectrometer was also used but only for proof of concept of this technology, operates from 420 to 740 nm at 15 fps using a 1024 by 1024 focal plane. All data collected was given to the sponsor and not discussed or shown herein.
