Tomographic approaches to hyperspectral imaging, such as CTHIS13 (Chromotomographic Hyperspectral Imaging Sensor), can eliminate the need for the slit, filter, or resonant cavity and substantially increase the optical throughput of the system. These systems capture most of the photon energy from the entire spectral band over the entire measurement interval. Uncooled LWIR imaging technology uses thermal based detecting elements that are less sensitive than the competing photon based cooled detecting elements, and require high optical throughput. An uncooled LWIR hyperspectral imager is described that combines a new high optical efficiency spectral imaging technique combined with a high performance uncooled thermal imager. The merging of these technologies in the current invention will significantly reduce the size, weight, and power requirements of LWIR hyperspectral systems.
