1. An apparatus comprising:
a light sensor having directional sensitivity, the light sensor including a plurality of light sensitive elements disposed on a substrate;
a plurality of metal layers deposited on the substrate and having openings that define a size of a single aperture, at least one metal layer having an opening that is larger than an opening of another metal layer of the plurality of metal layers disposed on the at least one metal layer,
wherein the plurality of light sensitive elements are disposed below the single aperture, and
wherein each of the light sensitive elements has a respective field of view through the single aperture that differs from the field of view of the other light sensitive elements.
