Abstract:
1. An image sensor comprising: a beamsplitter to encode incident light with a set of two orthogonal polarizations including a first polarization and a second polarization, wherein the incident light includes light polarized to the first polarization corresponding to a first view of a three-dimensional object and light polarized to the second polarization corresponding to a second view of the three-dimensional object; a pixel array comprising a plurality of pixel units arranged in rows and columns, each pixel unit including at least one imaging pixel; a polarizer array optically coupled to the pixel array to filter the incident light, the polarizer array comprising a plurality of polarizing filters wherein each pixel unit in the pixel array is optically coupled to a corresponding polarizing filter in the polarizer array, and wherein the polarizations of all polarizing filters in the polarizer array are selected from the set of two orthogonal polarizations consisting of the first polarization and the second polarization; wherein each imaging pixel comprises:
