Abstract

An improved Brewster angle technique for measurement of the refractive index of transparent materials in the form of thick and geometrically nonuniform layers on a much thicker substrate is presented. The technique’s usefulness is demonstrated in application to the dichromated gelatin layers.

Examples of the dependence of the intensity of the reflected light on the angle of incidence. The line marked with triangles represents the intensity of the light reflected from the DCG–glass interface; the pointed line shows the interference result for all three reflections; the remaining solid lines show the intensity of the light reflected by the gelatin layer only for three different thicknesses of the gelatin layer 20.0, 20.1, 20.2 μm.
