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.
