摘　　要：劈尖干涉是大学物理实验中的重要教学内容。延伸应用劈尖干涉实验技术和方法,寻找干涉条纹变化与长度微小变化量之间的关系,研究测量长度微小变化量的新方案,分析微小长度缓慢连续变化和突变情况下的测量问题,对培养大学生的实验创新能力具有一定的指导意义。Wedge interference is important teaching content in college physics experiment. In this paper, the technology and method of wedge interference experiment is extended, the relationship between interference fringe width and length variation is discussed, and a new scheme for measuring the change of length is put forward, which can measure the slight length under continuous change and break change. It has a certain guiding significance to cultivate the technological innovation ability of college students.
