摘要

The near field of ultrasonically diffracted light is examined for a wide range of Raman-Nath (v) and Klein-Cook (Q) parameter values up to the region of total light rediffraction phenomenon occurrence to the zeroeth diffraction order. The behavior of the secondary interference plane position is studied, both theoretically and experimentally, for various Q and v values. In addition, the relationship is shown between diffracted light intensity modulation minima localization shift and rediffrac-tion phenomenon. A comparison is made of the results of the general Fresnel region theory, including the influence of complex light amplitudes over the diffracted light intensity distribution, with those obtained from Cook's simplified near-field description. The same, limited validity range of the latter theory is revealed. For all the experimental conditions considered, quite good agreement is observed between experimental data obtained and the appropriate theoretical predictions. # 1999 Society of Photo-Optical Instrumentation Engineers.
