Description: Two-dimensional fast Fourier transform method for interferogram processing, due to the sampling of the data sequence length must be 2 n times, so the range of data required to interferogram Extension circular region into a rectangular area, the paper proposes a reconstruction based on block interferogram algorithm principles and methods of extension, the use of this method was a practical extension interferogram, the results show that the principle method has a high processing precision, the wavefront phase recovery basis.
