【Abstract】 In this paper on the basis of one-dimensional acousto-optic Raman-Nath diffraction analysis, the light spot energy, the modulation spectra and the relation between the direction of the diffraction array and the modulation acoustic wa\ c under two-dimentional diffraction are derived. The experimental results are given and the relation between one-dimentional and two-dimentional diffraction are analyzed. The two characteristics of multidimensional Raman-Nath diffraction are also presented.更多还原
