Abstract: This paper describes a new angular displacement interferometer based on the internal-reflection effect. In order to make use of the internal-reflection effect, a novel prism assembly is designed, which yields a very compact optical configuration. As a result, the linearity of the angular displacement interferometer is greatly improved. Both the linearization of the measurement equation and the experimental verification of the analysis have been conducted and the results are presented here in detail. The main factors affecting the angle measurement are also addressed. The results of the experimental verification are in good agreement with the theoretical analysis.
