The concept of a passive far-field imaging system, using a unique spatial-spectral multiplexing (SSM) technique, is presented. The described SSM technique uses spectrally resolved interferometry to multiplex a scene’s angular spectrum onto the power spectrum, while dispersion characteristics are implemented to heterodyne the channeled spectrum into the spectral range of visible light. In this paper, the theory of the design is detailed and an analysis of the spatial and spectral tradespace of the system are discussed. Applications for this imaging technique are primarily focused in remote sensing and far-field target identification.
