摘要
对超声光栅的形成机理作了理论分析，指出一维运动的超声波进入液体经金属反射板反射形成驻波，使液体的密度、折射率和相位等物理性质产生周期性变化。
Theoretical analysis of the formation mechanism of ultra sonic photo grate is presented. It is pointed out that the formation of standing wave with the one dimensional ultra sonic wave after entering into the liquid and reflected by metallic baffle board makes the liquid properties such as the density, refraction index, and phase vary periodically, forming, then, an ultra, sonic phase photo grate.
