Sony’s New In-Camera Polarizer
Sony’s is developing a polarization sensor that can be embedded directly inside the camera, eliminating the need for external filters. Polarizing filters, which are used to reduce glare and reflections. The Sony sensor is made up of a metal grid that has been angled to four different polarization angles. The grid sits atop the camera’s photodiode, and the varying angles allow the photographer to choose the degree of polarization desired.
