Polarization camera from Lucid Vision Labs has four directional polarizing filters

The Phoenix polarization industrial camera features Sony’s IMX250MZR CMOS polarized sensor. A 5 Mpixel global shutter sensor with 3.45 μm pixels provides rates up to 24 frames/s. It has four directional polarizing filters (0°, 90°, 45°, and 135°) on every four pixels, and uses on-camera processing to output the intensity and polarized angle of each pixel.
