New 5 MP Polarization Cameras: A New Tool for Industrial Imaging
Published on September 27, 2019 by TIS Marketing.
Sony's Polarsens™ 5.1 MP global-shutter CMOS image sensors (IMX250MZR/ IMX250MYR) capture visual data which cannot be obtained using other standard monochrome and color sensors. The Imaging Source's new USB 3.0 and GigE polarization cameras feature the Polarsens technology which uses four-directional (0°, 45°, 90°, 135°) nanowire micro-polarizers placed in front of each 2x2 pixel array (calculation unit) to deliver multi-directional polarized images.
Many materials, such as plastics, glass, metals and liquids display intrinsic polarization properties which can result in glare and other image artifacts in standard intensity images.
The sensors' polarization filters make use of these polarization properties to visualize material stress and surface scratches as well as to reduce glare, improve edge detection or to enhance contrast in low-contrast materials.
The 5.1 MP cameras are available as color and monochrome variants with either a GigE (max. 24 fps) interface or a faster USB 3.0 interface (max. 75 fps). For additional information, please have a look at our whitepaper.
