Polarisation Reveals Details That Were “Invisible”
Polarisation Reveals Details That Were “Invisible”

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 polarisation filters, the sensor generates an image with four polarisation directions in a single image. Based on the intensity of each directional polarisation, the polarisation angle and the degree of polarisation can be determined.

This makes it versatile – for example, for checking residues on surfaces before further processing or for removing reflections for traffic monitoring. With dimensions of only 29 x 29 x 29 millimetres, the models are ideal for space-critical applications.
