Sony Semiconductor Solutions has launched a polarization image sensor (polarization sensor): 3.45µm pixel size with four-directional polarizer which is formed on the photodiode of the image sensor chip. This polarization sensor is targeting the industrial equipment market.
In addition to capturing brightness and color, this image sensor can also capture polarization information that cannot be detected by a normal image sensor. This polarization sensor can be used in many applications in the industrial field, such as inspection when visibility and sensing are difficult.
Polarsens is a CMOS Image Sensor pixel technology that has several different angle polarizer formed on chip during the semiconductor process allowing highly accurate alignment with pixel.
