Abstract: An incident beam of natural light is divided into two beams of linear polarized light, their polarizations being mutually perpendicular. One beam is directed to a specimen surface and the other to a reference surface. Upon reflection from their respective surfaces, the beams are recombined and analyzed. The resultant of this recombined beam is a linear polarized beam having a certain orientation which is a function of the difference in optical path of the two beams. This optical path difference relates to the magnitude of imperfections of the specimen surface under observation.
