POLKA is an innovative camera for pixelwise detection and measurement of the polarization state of light. POLKA captures all the relevant polarization parameters in a single shot at a read-out rate of up to 25 images per second.
At the core, a custom-made CMOS image sensor with on-chip polarizers is employed, making external filters or costly mechanics obsolete.
For seamless integration into existing machine vision workflows, POLKA features an industry standard GigE Vision or USB3 Vision interface. The camera is ready to go in no time without any mechanical calibration. Its standard C-mount lens adapter enables the user to quickly adjust the cameras optical properties to suit different applications, and also accommodates standard lenses.
Though being compact and rugged, POLKA is an artefact-free, cost-effective and easy to calibrate solution whenever the polarization information of light is to be analyzed. Real-time calculation of intensity, direction and degree of polarization and visualization as pseudo-colour image makes this information available for human eyes – uncover the Invisible!
