We present a single disperser spectral imager that exploits recent theoretical work in the area of compressed sensing to achieve snapshot spectral imaging.
An experimental prototype is used to capture the spatiospectral information of a scene that consists of two balls illuminated by different light sources.
An iterative algorithm is used to reconstruct the data cube. The average spectral resolution is
