基于光拍频法测量光速的实验光路，分析了光束传播偏离理想光路产生的误差。一方面，光束传播的偏离会引起附加的光程差；另一方面，它也会造成光探测器的光敏面接收光信号的位置发生改变，造成虚假相移。建立模型并结合实验观测的数据，定量地分析了它对实验造成的相对误差，并提出了在实验中减少误差的可行方法。

The error originated from the deviation of trajectory of light had been investigated in measuring the velocity of light using the optical beating method .On the one hand ,an additive optical path difference would be induced by the deviation of light trajectory in the experiment .On the other hand ,there would be a change of the spot position on the photosensitive surface of the optical detector leading to a fictitious phase shift .Based on the model established ,the relative error due to the devia‐tion was quantitatively analyzed combining with the experimental results .In addition ,an error reduc‐ing method had been put forward .
