摘要
介绍了利用溴化亚铜激光器输出的脉冲激光通过光纤延时的方法测出光波波包中心所通过的光程及所需时间,从而实现测定光速的实验开设及其设计思想.
An experiment measuring light speed and the thoughts of its design are introduced. By using a fiber to postpone light pulse output from CuBr laser, the light speed can be determined by the time that light wave packet center traversed.
