Quantitative imaging for optical field via a single-pixel detector

Quantitative phase imaging (QPI) is important in many applications such as microscopy and crystallography. To quantitatively reveal phase information, people could either employ interferometric pictures for phase shift calculation, or utilize diffraction patterns for phase retrieval reconstruction. Traditionally, both of these two ways use pixelated detectors. In this work, a novel QPI scheme is designed inspired by single-pixel camera (SPC), …
