多维声光衍射和多维声光器件

Multiple dimensional acoustooptic diffraction and multiple dimensional acoustooptic device

本文建立了沿不同方向的多个超声波信号作用下的多维声光衍射的耦合波方程,并求出相应的解。分析了多维声光衍射的衍射效率、压缩、交叉调制和互调制强度等特性。用我们研制的多维声光器件进行了实验测量,实验结果与理论分析一致。

A set of coupled wave equations for multiple dimensional acoustooptic diffraction with multiple acoustic waves along different directions is put forward and its solutions are derived. The characteristics of the diffraction efficiency, compression, cross modulation, and intermodulation intensities are analysed theoretically. The theoretical results are supported by experimental measurements through our new multiple dimensional acoustooptic devices.
