Polarisation helps to reveal often hidden details

04 May 2020

IDS has added 5 megapixels polarisation cameras to its product portfolio with the addition of the Sony IMX250MZR 5 MP polarisation sensor, with integrated on-pixel polarisers, its uEye CP camera family.

The models are said to offer 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 offers versatility – for example, for checking residues on surfaces before further processing or for removing reflections for traffic monitoring.
