光学组件代替光强探测器改进双棱镜实验

Biprism Laser Interference Experiment Using Optical Components Instead of Light Intensity Detector

该文对激光双棱镜干涉实验进行了改进。针对使用光强探测器测量干涉条纹造成的一系列问题,采用光学组件代替光强探测器,解决了激光光强较大易致观察者视力疲劳、光强探测器测量操作易出错等问题。改进后的实验没有引入附加误差因素,不需要降低激光光强,并恢复了测微目镜的优点。实验结果表明,得到的干涉图像清晰易辨,实验测量操作简易,测量结果准确可靠。

This paper focuses on improving biprism laser interference experiment.To solve fatigue problems and operation errors caused by laser＇s intensive light and light intensity detector respectively,optical components are introduced as an alternative solution.There＇s no additional error factor involved,don＇t need to reduce laser output intensity,and also preserve the merits of micrometer ocular.The acquired pattern is clear to identify,operations remain simple,and measuring results are accurate and reliable.
