Abstract
The invention relates to a method and apparatus for determining the polarization properties of light emitted, reflected or transmitted by a material using a laser scanning microscope with the tested material being illuminated point by point with a laser beam of known polarization state. According to the invention the light beam with a polarization state modified by the material or the light emitted by the material is being examined by measuring the intensity of two different polarization components of a selected light beam received from each point of said material essentially at the same time and assigning a signal obtained by processing the two intensity signals to a respective point of an image of said material. The apparatus has a polarization state generator between the laser light source and the material being tested, and a detector in a light beam for determining the intensity of light with a polarization state modified by the material or the intensity of light emitted by the material, the improvement of which is that a means for dividing the polarization components in space or time is used in front of the detector.
