A SINGLE-SHOT DIFFERENTIAL PHASE CONTRAST QUANTITATIVE PHASE IMAGING METHOD BASED ON COLOR MULTIPLEXED ILLUMINATION

A single-shot differential phase contrast quantitative phase imaging method based on color multiplexing illumination. A color multiplexing illumination solution is used to realize single-shot differential phase contrast quantitative phase imaging.
