| Abstract: | Based on the transmission theory of Gauss beam , the interference effect of reflection beams from a single layer film-substrate was studied. The related theoretical intensity profile of interference fringe wa s obtained. In terms of the theory, the characteristics of the interference frin ge and the influence of some main factors on the fringe were analyzed. The exper iments, which were carried out with a single layer film-substrate and the glass substrate showed that the theoretical analysis is correct. |
