Abstract
An imaging device includes a plurality of optical sensors on an integrated circuit and a plurality of sets of interference filters, where a set of interference filters of the plurality of sets of interference filters includes a plurality of interference filters that are arranged in a pattern with each interference filter of a set of filters being configured to pass light in a different wavelength range. A plurality of sets of absorption filters is included, with a set of absorption filters of the plurality of sets of absorption filters including a plurality of absorption filters arranged in a pattern and each absorption filter is associated with one or more interference filters to create an absorption filter and interference filter pair. Each absorption filter and interference filter pair is associated with one or more optical sensors and is configured to pass light in a narrower wavelength range than the absorption filter alone.
