利用光纤延时实现光速测定的实验研究

Experimental Study on Measurement of Velocity of Light by the Fiber Delay Time

介绍了光纤延时法实现光速测定的实验设计思想.利用光纤对溴化亚铜激光器输出的脉冲激光进行延时,通过常规测长手段测得光纤的几何长度并用示波器测出两相邻光脉冲间的时间间隔,即可获得光速.

This paper introduces the experimental setup for measuring velocity of light and thought of its design. By using a fiber to delay the pulse light of CuBr laser, velocity of light can be obtained with geometry length of fiber and time interval between two light pulses.
