摘要：

A method of direct retrieval of deformed wavefront by phase unwrapping using two-dimensional Fourier transform was presented. The projection data of any axial cross-section can be extracted to implement three-dimensional tomography in full meaning. The simulated temperature field experiment proves that the projection data extraction method based on phase unwrapping can be used for facilitating the computation of tomography.
