| 摘 要： | 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。

| Abstract: | We propose a new method to measure wavelength of light by laser interferometer. Different interference 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 relationship of the number of varied interference fringes、the angle of a transparent glass and the thickness of the glass. |
