摘要
当一束激光照射在金属丝上时,在垂直于金属丝的屏幕上会出现环形的光.本文分析了光环产生的物理机制,计算模拟各参数对光环形状的影响。并通过实验进行了定量探究。
When irritating a laser beam on a metal wire,a light ring will appear on the screen.In this article we analyzed the formation mechanism of the light ring,and discussed how relative parameters influence the light ring by theoretical calculation,simulation,and experiments.
