Abstract

In the method described, two coherent light beams are directed at the partially transmitting film in such a way that two new beams are emitted. A comparison between the intensities of the outgoing beams enables one to determine the thickness, refractive index, and absorption coefficient of the film. One advantage of the method is that no absolute values of light intensities or polarization must be determined. This part of the work describes the basic theory of the new method. Experimental verification of the theory and further analysis of the characteristics of the method are left for Part 2.
