Abstract A single-shot procedure to reduce speckle noise in numerically computed unwrapped phase maps is proposed. The method is supported on the possibility of expressing the computed phase maps as phasors in the complex plane to understand the phase denoising as a pointwise iterative operation of phasor tuning. Notwithstanding in this work the method is applied in digital holographic microscopy, it could be utilized in any other technique where an unwrapped phase map can be obtained. Numerical modeling and experimental results with non- and –biological samples are presented to support the feasibility of the method.

用于相位波场中单次散斑降噪的逐点相量调谐

摘要 提出了一种在数值计算的展开相位图中减少散斑噪声的单次程序。该方法支持将计算出的相位图表示为复平面中的相量的可能性，以将相位去噪理解为相量调谐的逐点迭代操作。尽管在这项工作中，该方法应用于数字全息显微镜，但它可以用于任何其他可以获得展开相位图的技术。提供了非生物和生物样品的数值建模和实验结果，以支持该方法的可行性。
