Abstract:
1. An apparatus, comprising: an array of sub-diffraction limit-sized light receptors formed in a substrate having a light receiving surface, each sub-diffraction limit-sized light receptor is configured to output a binary valued bit element and to change state between an off-state and an on-state by the absorption of at least one photon; and an optical filter structure disposed over the light receiving surface, the optical filter structure comprised of an array of filter pixels with each filter pixel having an associated passband spectral characteristic, and where a data element obtained from said array of sub-diffraction limit-sized light receptors is comprised of a plurality of said bit elements output from a plurality of sub-diffraction limit-sized light receptors that underlie filter pixels having at least two different passband spectral characteristics.
