Title:
DEVICE, METHOD AND COMPUTER READABLE STORAGE MEDIUM FOR QUANTITATIVE PHASE IMAGING
Document Type and Number:
WIPO Patent Application WO/2023/083042
Kind Code:
A1
Abstract:
A device, a method and a computer-readable storage medium for quantitative phase imaging are provided. The method comprises: obtaining a multiplexed interferogram of a sample, where the multiplexed interferogram is an imaging map captured by a camera when a sample beam composed of at least two beams with different wavelengths to illuminate the sample and then penetrate into at least two cubic beam splitters to combine with the at least two beams with different wavelengths as reference beams; and performing a phase retrieval on the multiplexed interferogram to obtain a phase map of the sample at the wavelength of each beam that composes the sample beam. The device is compact and ease-of-use, and can realize versatile measurement functions for more comprehensive studies in biology and material studies.
