A polarisation sensor makes details visible that remain hidden to other image sensors. IDS now offers the IMX250MZR 5 MP sensor from SONY with integrated on-pixel polarisers in the uEye CP camera family. The models ensure better object detection in cases of low contrast or light reflections. They also provide a convenient way of detecting fine scratches on surfaces or the stress distribution within transparent objects.
Both USB3 Vision and GigE Vision are available as interfaces. Using a polarisation filter, the sensor generates an image with four polarisation directions in a single image. Based on the intensity of each directional polarisation, the polarisation direction and the degree of polarisation of the light source can be determined. With predefined, selectable image components, the user can, for example, filter out disturbing light reflections directly from the sensor raw data or make reflective object features visible in almost complete darkness even before the image is transmitted to the PC – and all with just one click!
FPGA-accelerated algorithms thus make the cameras more than just suppliers of sensor data. They provide meaningful evaluations in real time, which can be used by any GenICam-compliant application via GigE or USB3 Vision interface. IDS polarisation cameras thus can also reduce the computing load of the host PC.
Thanks to their innovative, patented housing design and the very high manufacturing quality typical of IDS, the compact industrial cameras also make designers’ hearts beat faster. With dimensions of only 29 x 29 x 29 millimetres, the models are ideal for space-critical applications. Screwable cables also ensure a reliable electrical connection.
