摘要
通过简单的理论计算及与平面透射光栅的对比 ,阐述声光调制器的工作原理 ,并给出一幅比较清楚的物理图像 ,以加深学生对实验的理解和知识面的拓展。
The working principle of photo-acoustic modulation was described through a theoretical analysis and by the comparison with transmitting grating.A clearer physical picture was obtained for the process of the photo-beating.Therefore students can understand the experiment thoroughly,and their knowledge can be broadened extensively.
