Abstract
An optical sensor includes an array of pixels configured to convert photons into electrons for forming an image or to measure spectral content without forming an image. A filter assembly is operatively associated with the array of pixels for passing predetermined bandwidths of photons to the array of pixels. A mask is operatively associated with the array of pixels and the filter assembly. The mask includes a plurality of apertures each for limiting photons passing through the filter assembly to a respective pixel in the array of pixels.

An optical sensor comprising:
- an array of pixels configured to convert photons into electrons for forming an image;
- and
- a filter assembly operatively associated with the array of pixels for passing predetermined bandwidths of photons to the array of pixels, wherein the filter assembly includes a plurality of filters defining an intra-filter space therebetween, wherein a mask is defined within the intra-filter space to prevent photon leakage from one filter to another.
