Speckle-moire phenomenon based on the study of speckles polarization for multieffect simulated biotissue

摘要

Based on the study of speckles polarization for multi-effect simulated biotissue, a new phenomenon called speckle-moire is created within a single diffraction halo of a laser specklegram. This is made by controlling the correlation between selected speckle pairs within a multiexposure specklegram via the polarization properties of laser speckles. This phenomenon can be used to measure the difference between two displacements or deformations processes, such as, in the field of speckle metrology for biomedical science.
