high-resolution label-free phase and polarization tomography

Fourier ptychography (Konda et al., 2020) is a quantitative phase imaging method that creates high resolution, wide field microscopic images. In this post, we will introduce our works that highlight vectorial nature of light (Xu et al., 2022; Xu et al., 2022), as well as works that explores its speed limit (Yang et al., 2021; Sun et al., 2019).
