使用迈克耳孙干涉仪通过旋转样品测量透明玻璃厚度。与白光干涉原理测薄片厚度不同,实验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,使相干光的干涉条纹发生变化,利用干涉条纹与转过角度、透明玻璃厚度之间的关系,通过实验准确测量出透明玻璃的厚度。
使用邁剋耳孫榦涉儀通過鏇轉樣品測量透明玻璃厚度。與白光榦涉原理測薄片厚度不同,實驗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,使相榦光的榦涉條紋髮生變化,利用榦涉條紋與轉過角度、透明玻璃厚度之間的關繫,通過實驗準確測量齣透明玻璃的厚度。

A rotating sample method to measure the thickness of transparent glass wafer was pro-posed using a Michelson interferometer .In comparison to the traditional method based on the interfer-ence of white beams ,the different interference fringes were generated by changing the angle between the wafer and the light .The thickness of the transparent glass wafer was accurately measured accord-ing to the changes of the fringes and the rotation angle .
