Abstract: An optical sensor system includes a plurality of sets of optical sensors implemented on a substrate, with a plurality of sets of optical filters, wherein a set of optical filters of the plurality of sets of optical filters is associated with a set of optical sensors and a set of optical filters of the plurality of sets of optical filters includes a plurality of optical filters that are arranged in a pattern, with each optical filter of the plurality of optical filters configured to pass light in a different wavelength range of a predefined spectral range. Each set of optical filters operates to provide a bandpass response corresponding to the predefined spectral range and a set of optical filters is located atop an associated set of optical sensors, where at least two sets of optical filters of the plurality of sets of optical filters are configured to provide different bandpass responses. An optical element is associated with a corresponding set of optical sensors, with each rejection filter configured to pass light wavelengths in a predefined spectral range.

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.
