The unique Sony Polarsens IMX264MZR sensor detects the polarization of light. This sensor is based on the popular 2448 x 2049 pixel, 2/3” IMX264 CMOS sensor with 3.45 μm pixel size. A four-directional polarization filter using nano-wires is overlaid directly on top of the pixel array and beneath the micro lenses. This filter consists of repeated 2 x 2 patterns of grid polarizers with four different angles: 0, 45, 135 and 90 degrees. Each polarizer filters the incoming light so that only the polarization components perpendicular to the grid orientation can pass through and be detected by the underlying photo-diode. A four-direction polarization image can be captured in a single shot.
