A novel spectral imaging sensor based on dual direct vision prisms is described. The prisms project a spectral image onto the focal plane array of an infrared camera. The prism set is rotated on the camera axis and the resulting spectral information is extracted as an image cube(x, y, 1), using tomographic techniques. The sensor resolves more than 40 spectral bands (channels) at wavelengths between 1.2 microns and 2.5 microns ...
