Abstract：In order to cultivate students' innovative awareness and exercise their ability to apply what they have learned, a Young's modulus measuring device that can realize various optical measurement methods has been designed by combining the basic structure of the existing Young's modulus measuring instrument in physics laboratory teaching with an optical rail. Based on this device, the Young's modulus of a metal wire has been measured using both the Moiré fringe method and the single-slit diffraction method. The experimental phenomena are distinct, and the difficulty of optical path adjustment has been reduced. Analysis of the experimental results shows that compared with the traditional optical lever method, the experimental accuracy has been significantly improved. This proves that the experimental device has good comprehensiveness and expandability. More measurement methods can be developed based on this device in the future to enrich the content of learning and research.
