摘要
一种迈克尔逊双透射光干涉测激光波长的方法,该方法巧妙地提高了干涉仪的灵敏度,并将条纹吞吐的现象转化为观察屏上的明暗变化,同时可以灵活改进计数方法,减少实验工作量。该方法思路简单,易于实现,有利于拓展思维。
We proposed the double transmission light interference experiment, which can skillfully rise the sen- sitivity of Michelson interferometer and transform the variational fringes into the bright and dark change on vie- wing-screen.Meanwhile, experimental workload can be reduced by improving count method flexibly.The method is simple and easy to realize, in favor of pioneering thinking.
