| Abstract: | A new method of observing equal-thickness interference of transmitted light is introduced,and it will enrich the equal-thickness interference.By interference theory of light,the intensity distribution of interference fringes is obtained under the condition of R<0.5.The fringe visibility is improved by means of coated glass in the experiment. Besides,the fringes of transmitted light are compared with the ones of reflected light. |
