Abstract:
1. A system for analyzing polarization properties of light, the system comprising: an optical element for collecting light; a polarization filter having an array of polarization cells in various directions of polarization, the array of polarization cells comprising a core array of filter cells comprising a horizontal polarization filter cell, a vertical polarization filter cell, a no-polarization filter cell and a circular polarization filter cell; a wavelength filter comprising a plurality of repeated sub-arrays of wavelength filtering cells in various colors, each sub-array wavelength filtering cells correspond to a respective polarization cell of said polarization filter; and an image sensor comprising an array of image sensor cells, wherein at least one of said sub-arrays of wavelength filtering cells corresponds to a respective polarization cell of said polarization filter and to a respective group of cells of said image sensor, so that each image sensor cell in said respective group of cells is configured to receive light that passed through both a respective polarization cell and a respective wavelength filtering cell.
