Snapshot Phase-Shifting Diffraction Phase Microscope
This invention proposes combining snapshot phase-shifting interferometry with high resolution polarization imaging to create quantitative phase maps from diffraction microscopy. A polarization grating separates the incident beam into object and reference beams, and a digital camera captures four phase-shifted interferograms from polarization filters...

Phase Unwrapping by Neural Network
This document in-part describes systems and methods that can be used to facilitate reliable and accurate phase unwrapping. The techniques that can be implemented to obtain unwrapped phase using segmentation approaches. The techniques are also robust against noises in the input data, thereby providing fast and reliable unwrapped phase results. Background:...
