| 摘 要： | 提出广义相移干涉术中结合广义四步公式改进最小二乘法抽取任意相移进而重建复波的方法.利用广义相移数字全息算法的物波重建公式替代传统最小二乘法来提取参考光相位和重建物体波前,大幅减小迭代循环的计算量.使用该方法,每一次迭代计算参考相位只需要一个最小二乘法,同时利用物波前重建公式计算物光相位.这种方法的可行性和有效性已被计算...

| Abstract: | An approach of unknown phase shifts extraction and complex wave reconstruction in generalized phase-shifting interferometry is proposed by the combination of least square methods and generalized four-step formulae.A much-simplified algorithm is suggested to extract reference phase and then reconstruct object wave-front by replacing the conventional least-square method in above process with our specially derived wave reconstruction formulae for generalized phase-shifting interferometry.In this method,only on... |
