Abstract:
1. A spectral imaging system, comprising: a plurality of spectral units arranged in an array, each spectral unit of the plurality of spectral units comprising: a microlens having an optical axis; a spectral filter having a center wavelength and aligned with the optical axis, the spectral filter comprising an interference filter and wherein the center wavelength of each spectral filter varies according to an incident angle light impinging upon the spectral filter; a fiber optic bundle, the fiber optic bundle having a curved light receiving surface and a planar light output surface, wherein the curved light receiving surface is aligned with the optical axis and coincides with a surface of geometric foci of planes waves transformed by the spectral unit's spectral filter and microlens; and a plurality of pixel sensors configured to receive light from the planar light output surface of the filter optic taper portion.
