| Abstract: | Applied CCD camera and digital electronic technologies, a new photoelectric experimental instrument for equal thickness interference is developed. It is able to not only display the magnified fringe of equal thickness interference in the monitor, but also perform digital reading and measurement for the fringe. Its structure and measurement principle are introduced. The operating method of the experiment of "Determination of the radius of curvature of lens using Newton ring" by this instrument is described, and the measuring results are remarked. |
