Abstract

Recent advances in dual band infrared focal plane technology now enable the design and testing of a dual infrared band snapshot imaging spectrometer, the first-ever of its kind. A review of proof of concept results from a dual-visible-band Computed Tomographic Imaging Spectrometer (CTIS) system is presented. The dual-visible system demonstrates that it is possible to reconstruct two spatially co-registered hyperspectral data cubes covering different spectral bands. Based on the visible band CTIS proof of concept, a similar infrared system is now proposed. Critical to the CTIS system is the design of the Computer Generated Holographic (CGH) disperser. Several different (CGH) designs are considered. A first order optical design for the dual infrared band CTIS is presented.
