TL;DR: In this article, a matched annular illumination was proposed to boost the phase contrast for low spatial frequencies, and significantly improved the practical imaging resolution to near the incoherent diffraction limit, achieving a transverse resolution up to 208 nm.

TL;DR: A new era in which strict coherence and interferometry are no longer prerequisites for quantitative phase imaging and diffraction tomography is highlighted, paving the way toward new generation label-free three-dimensional microscopy, with applications in all branches of biomedicine.

TL;DR: Fourier ptychographic diffraction tomography (FPDT) as mentioned in this paper iteratively stitches together variably illuminated, low-resolution images acquired with a low-numerical aperture (NA) objective in 3D Fourier space to create a wide field-of-view (FOV), high-resolution, depth-resolved complex refractive index (RI) image across large volumes.

TL;DR: In this paper, a label-free, scan-free intensity diffraction tomography technique utilizing annular illumination (aIDT) was proposed to rapidly characterize large-volume 3D refractive index distributions in vitro.

TL;DR: This work proposes an adaptive pixel-super-resolved lensfree imaging (APLI) method which can solve, or at least partially alleviate, limitations of typical lensfree microscopes and addresses the pixel aliasing problem by Z-scanning only, without resorting to subpixel shifting or beam-angle manipulation.
