This Letter proposes a method to estimate phase derivatives of arbitrary order in digital holographic interferometry. Based on the desired order, the generalized complex-lag distribution is computed from the reconstructed interference field. Subsequently, the phase derivative is estimated by tracing the peak of the distribution. Simulation and experimental results are presented to validate the method's potential.
这封信件提出了一种在数字全息干涉计量术中估计任意阶相导数的方法。基于所需的阶数,从重建的干涉场中计算广义复滞后分布。随后,通过跟踪分布的峰值来估计相导数。给出了模拟和实验结果,以验证该方法的潜力。
