| 摘 要： | 提出用傅里叶变换进行干涉图相位展开（ＰｈａｓｅＵｎｗｒａｐｐｉｎｇ）的办法直接恢复变形波面，从而可以提取轴向任意截在上的投影数据，实现真正意义上的三维层析，模拟温度场实验证明基于相位展开的投影数据提取方法能够更好的完成层析计算。

| Abstract: | A method of direct retrieval of deformed wavefront by phase unwrapping using 2 D Fourier transform is presented. The projection data of any axial cross section can be extracted to implement 3 D tomography in full meaning. A simulated temperature field experiment proved that the projection data extraction method based on the phase unwrapping succeeded in facilitating computation of tomography. |
