Abstract

An optical sensor system comprises an array of optical sensors arranged on an integrated circuit and a plurality of filters with the bottom surface of the plurality of filters located above the top surface of the array of optical sensors. The optical sensor system further comprises an angle-of-incidence layer that includes a top surface, a bottom surface, and a thickness Y, where the bottom surface of the angle-of-incidence layer is located a predetermined distance X from the top surface of the plurality of filters and the angle-of-incidence layer includes a plurality of collimating elements, with each collimating element of the angle-of-incidence layer having an aperture width Z.
