Complex-valued speckle effect and its suppression for high quality of phase unwrapping reconstruction in coherent digital holographic microscopy

W Lu, Y Shi, J Yue, M Zheng, M Wang, J Wu - Optics Communications, 2020 - Elsevier
In coherent digital holographic microscopy, speckle noise is incorporated into the hologram
so that phase reconstruction may become worse in quality. Meanwhile, the previous speckle …
