Automatic cross filtering for off-axis digital holographic microscopy

open access: yesResults in Physics, 2020
Off-axis digital holographic microscopy (DHM) is a significant quantitative phase imaging (QPI) modality in a single shot. However, the reconstructed quality of the image in the off-axis DHM is governed by the spatial filtering in the spectral domain of ...
