用激光对传统牛顿环装置进行演示的探讨

Discussion on the Pemonstration of Traditional Newton's Ring Unit with Laser

通过试验,在牛顿环的中心发现了亮斑,并且仅用一个平凸透镜演示出了牛顿环,出现的牛顿环不是空气隙的两个界面反射的光进行干涉的结果,用激光对传统牛顿环装置进行演示是不妥当的。

The experiment shows that a bright point appears in the center of the newton's ring and the newton's ring is obtained on the screen with only one convex. It is pointed out that the newton's ring is not the interference result of the two rags reflected at the both interfaces between the air shim. Therefore the demonstration of traditional newton's ring unit with the laser is inappropriate.
