New 5 MP Polarization Cameras: A New Tool in Industrial Imaging
The Imaging Source has begun series production on four new cameras featuring Sony’s Polarsens™ 5.1 MP global-shutter CMOS image sensors (IMX250MZR/ IMX250MYR). These sensors capture visual data which cannot be obtained using other standard monochrome and color sensors. Sony’s Polarsens technology 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. The sensors’ polarization filters make use of this to visualize material stress and surface scratches as well as to reduce unwanted glare, improve edge detection or to enhance contrast in low-contrast materials. The supplied IC Measure software supports various methods of processing the 2x2 pixel arrays. 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).
