提出了一种利用激光干涉仪测量光波波长的方法。通过改变在光的传播路径上垂直放置的透明玻璃与光传播方向的角度，使相干光的光程差发生变化；利用干涉条纹与转过角度、透明玻璃厚度之间的关系，通过激光干涉实验能准确测量出光波的波长。
提齣瞭一種利用激光榦涉儀測量光波波長的方法。通過改變在光的傳播路徑上垂直放置的透明玻璃與光傳播方嚮的角度，使相榦光的光程差髮生變化；利用榦涉條紋與轉過角度、透明玻璃厚度之間的關繫，通過激光榦涉實驗能準確測量齣光波的波長。

We propose a new method to measure wavelength of light by laser interferometer. Different interfer-ence fringes are generated by changing the angle of a transparent glass wafer with the propagation direction of light. We prove the method can be used to measure the wavelength of light in experiment by deducing a rela-tionship of the number of varied interference fringes、the angle of a transparent glass and the thickness of the glass.
