Development of a video-rate snapshot hyperspectral sensor for tracking moving targets

ABSTRACT: This proposal focuses on the development of a novel video-rate snapshot hyperspectral sensor (VSHS) that can provide large format datacubes at 50 frames per second with a signal-to-noise ratio (SNR) of over 200 in every wavelength band. Its measurement principle is based on Image Mapping Spectrometry (IMS), a technique recently developed at Rice University and exclusively licensed to Rebellion Photonics. As a snapshot method, it contains no moving parts or dynamically adjustable components, and thus can image fast moving targets while guaranteeing a high SNR, compact size, low power consumption, and increased durability. As a non-computational technique, it is not prone to reconstruction artifacts and can deliver data in real time, and as a non-scanning technique, it does not require image post-processing to correct for spectral or spatial misregistration. BENEFIT: Our ultimate goal is to provide the VSHS in a highly portable form, e.g. similar to a large SLR camera working in the infrared spectrum with the aim to allow remote detection of various organic compounds. The DOD will have many uses for this product in addition to aerial surveillance and target tracking, some of these applications could include: improvised explosive device (IED) detection, missile target verification, and discovery of camouflaged objects. In addition, the technology can also be applied to many non-military applications. Chemical companies can use the VSHS to detect and quantify chemical leaks from the piping at their plants. Oil companies can use this device for oil exploration and it will also be used in the agriculture industry for improving the quality of their crops.
