摘　　要：通过设计一个简单的马赫-曾德干涉光路,得到合适的干涉条纹。通过演示实验者倚靠实验平台、在光路附近说话、在平台附近走动以及楼层振动等干扰条件,利用光强传感器实时监控条纹的变化,表征了上述振动干扰对条纹漂移的影响。上述结果对于学生直观理解全息照相过程条纹漂移的干扰因素将有一定帮助,同时有利于学生在实验过程中避免上述问题,提高全息照相实验成功率。A simple Mach-Zehnder interferometric optical path is designed to obtain suitable interference fringes.By demonstrating the interference conditions such as the experimenter contacting the experimental platform,talking near the optical path,walking near the platform and floor vibration,the influence of the above vibration interference on fringe drift is characterized by using light intensity sensor to monitor the fringe changes in real time.The above results will be helpful for students to understand the interference factors of fringe drift in holographic photography directly,and help students avoid the above problems and improve the success rate of holographic photography experiment.
