Visualization of polarized light with simultaneous suppression of unpolarized beams.
Combining a rotating polarizer with an image-processing technique permits the visual identification of the linearly polarized beams present in a field of view. The resulting images show the polarizations in a scene, regardless of the orientation of their electric-field vectors, with simultaneous suppression of unpolarized light.
