| 摘 要： | 利用数字全息干涉术研究了超声驻波场的三维分布特征,由所记录的不同角度的超声驻波场的数字全息图,经数值再现,得到了超声驻波场的强度和相位差分布图,进而由迭代重建算法重建出超声驻波场的三维分布曲线。结果表明,数字全息干涉术与迭代重建算法相结合是测量与重建三维超声驻波场的一种方便有效方法。

| Abstract: | The three-dimensional distribution properties of acoustic standing wave field are studied using digital holographic interferometry. By numerically reconstructing the digital hologram,the intensity and phase distribution of acoustic standing wave field is obtained, from which the three-dimensional distributing curve of acoustic standing wave field is also reconstructed with Algebraic Reconstruction Techniques (ART) algorithm .It is shown that the digital holographic interferometry and Algebraic Reconstruction Techniques algorithm is a effective method for measuring and reconstructing three-dimensional acoustic standing wave field. |
