ABSTRACT:
A spectral imager includes an elongate light propagation medium that receives light at one end, has graded average spectral absorption properties in the elongate direction, and spectral detectors distributed in the elongate direction. The spectral absorption properties of the medium can be graded in both elongate and transverse directions. Both linear and two-dimensional arrays can be formed, enabling simultaneous hyperspectral detection.
