摘　　要：本文采用空-时序转换方法实时测量在Bragg衍射时连续、稳定的α—f曲线的全貌,以及相对光强分布随板流变化的动态过程.实验结果与声光相互作用理论相符合。This paper describes that the method of spatial sequence to be transformed into time sequence is used to measure the complete picture of the 伪-f curve that is of realtime. series and stability. This method is also used to measure dynamical process of variation in distribution of relative intensity of light, which varies with plate current as Bragg's diffraction. The experimental results coincide with the theory of acous-to-optics interaction.
