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.
Sibel Yorulmaz-Cokugur, Sensor Expert at FRAMOS, says: “Polarsens™ technology has changed the industry. The on-chip polarization brings significantly higher quality analysis and simplified application design“.
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.
Evaluation samples of Sony’s IMX264MZR and IMX264MYR will be available from October 23rd 2020, mass production starts in February 2021.
The industry and product experts at FRAMOS are available to support customers with the integration of these new sensors into their applications and projects. In addition, FRAMOS provides a broad range of support services for development, customization, and logistics.
