提出了一种在广义相移干涉术（GPSI）中提取任意未知相移并重建复杂物波的算法，该算法无需迭代过程和物波强度测量。该方法可用于任何帧号>或=2的GPSI。计算机模拟和光学实验都证明了该方法在较宽相移范围内的有效性，得到了非常满意的结果。
An algorithm to extract the arbitrary unknown phase shift and then reconstruct the complex object wave in generalized phase-shifting interferometry (GPSI) without the iteration process and measurement of object wave intensity is proposed. This method can be used for GPSI of any frame number >or=2. Both computer simulations with smooth and diffusing object surfaces and optical experiments have verified the effectiveness of this method over a wide range of phase shifts with very satisfactory results.
