Sony Semiconductor Solutions has launched the new on-chip polarizer sensor IMX264MZR (monochrome) and IMX264MYR (color). This 5 Megapixel sensor has a 2/3-type format and a pixel size of 3.45 µm. It reaches frame rates up to 35.7 fps at 12-bit (only) and has one ROI window.
These new CMOS Pregius sensors are equipped with a four-directional polarization square pixel array which can filter light from all four direction in a single capture. Sony’s polarization image sensor has a high extinction ratio helping to get glare free image by removing reflection.
Polarization sensor can be used to remove reflection in ITS applications which can make use of the polarization to distinguish direct light from reflection and achieve better shape-recognition of low contrast objects without the need for external polarization filters.
About Polarsens technology
Sony´s Polarsens is a CMOS Image Sensor pixel technology that has four different polarizer angles directly superimposed on chip, under each pixel’s micro lens, allowing highly accurate alignment with the pixel array. Compared to conventional sensors with polarizer situated on the cover, the shorter distance between the polarizer and the photodiode improves the extinction ratio and the incident angle dependence. Since the polarizer is formed during the semiconductor process, the shape, formulation and uniformity of polarizer, along with the mass productivity and durability of these sensors are excellent compared to conventional polarization sensors.
Furthermore, Sony Semiconductor Solutions’ Polarization sensor is covered with an anti-reflection layer which helps to further reduce reflectance and avoids flare and ghosting characteristics in the captured images. Polarsens technology has a Global Shutter read-out, high frame rates, ROI control and trigger modes to further improve the image capture performance.
