Abstract
A system for imaging a scene, includes a plurality of optical sensors arranged on an integrated circuit and a plurality of sets of interference filters, where each set of interference filters of the plurality of sets of interference filters includes a plurality of interference filters that are arranged in a pattern and each interference filter of the plurality of filters is configured to pass light in a different wavelength range, where each set of interference filters of the plurality of interference filters is associated with a spatial area of the scene. The system includes a plurality of rejection filters arranged in a pattern under each set of interference filters, where each rejection filter of the plurality of rejection filters is configured to substantially reject light of predetermined wavelengths. The system further includes one or more processors adapted to provide a spectral response for a spatial area of the scene associated with the set of interference filters.
