57 Zusammenfassung AB [EN] A system and method for detection and measurement of circular birefringences in materials that exhibit the Faraday effect. The method and apparatus permit detection of optical activities via the difference in the directions of propagation the left- and the right-circularly polarized light (components). A beam of light is directed at an interface formed by the optically active medium and another medium such that a difference in the angles of refraction and/or reflection and/or diffraction between the left- and the right-circularly polarized components of the light beam can be detected. The difference in the propagation directions between the two circularly polarized light components is measured on a position sensitive detector and/or is detected as an intensity difference.
