修正的Sagnac实验测量匀速运动光纤中对向传播光束的走时差
Modified Sagnac experiment for measuring travel-time difference between counter-propagating light beams in a uniformly moving fiber
摘要:
研制了一种光纤传输器,用于研究两束反向传播光束在匀速运动光纤中的走时差。我们的发现是,在一段长度为Δ 1的光纤中,无论它是匀速运动还是作圆周运动,都存在一个传播时间差Δ t = 2 vDeltal/c^2,它随光源和探测器以速度v运动。
英文摘要:
A fiber optic conveyor has been developed for investigating the travel-time difference between two counter-propagating light beams in uniformly moving fiber. Our finding is that there is a travel-time difference Deltat=2vDeltal/c^2 in a fiber segment of length Deltal moving with the source and detector at a speed v, whether the segment is moving uniformly or circularly.
