反常声光偏转器收发光路的可逆性研究

Research on Reversibility of Optical Propagation in Abnormal Acousto-optic Deflector

提出了一种卫星光通信终端中反常声光偏转器(反常AOD)的工作方式。基于反常布拉格衍射几何关系,获得了非宽带匹配模式下的Dixon方程,设计了收发光路可逆性实验验证系统。实验结果表明,反常AOD收发光路可逆。

An approach utilizing abnormal acousto-optic deflector （AOD） as the beam deflector is proposed. Based on the relationship of wave vector of Bragg diffraction, Dixon equations are obtained under non-broadband match model, and the experimental system verifying the reversibility of optical propagation is designed. Experiments results show that optical propagation is reversible.
