The Theoretical and Experimental Study of Two-Dimensional Multichannel Acousto-Optic Interaction

Zhao Qida He Shiya Yu Kuanxin ( Departmentof Applied Physics,Beijing Polytechnic University,Beijing1 0 0 0 2 2 )  
The interactions of two-dimensional multichannel parallel acoustic waves with an optical light beam are studied.A set of coupled wave equations for two-dimensional multichannel acousto-optic is put forward,and its solutions are derived.The linear and nonlinear effects of the principle diffraction from each channel and intermodulation of the two-dimensional multichannel acousto-optic interaction are analyzed theoretically.A new type of two-dimensional multichannel acousto-optic modulators is made,and its characteristics are measured.The theoretical analysis is supported by the experimental results.The matrix-vector multiplication operation has performed by use of the two- dimensional multichannel Bragg acousto-optic modulator.
