提出了相位展开方法，用单张干涉图实现干涉波前的恢复，获取相位物体的相位差信息，并将其应用于重建波面经过温度场引起的相位变化，且与条纹跟追方法比较，获得了良好的效果。
The method of phase unwrapping is proposed. The single wave interferogram is used to recover the interference wavefront, and the phase difference information of the phase object is acquired. The phase difference caused by the temperature field of the reconstructed wave surface is obtained and compared with the fringe and chase methods Good effect.
