Solving inverse scattering problems in biological samples by quantitative phase imaging

PDF Link

Quantitative phase imaging (QPI), a method that pre- cisely recovers the wavefront of an electromagnetic field scat- tered by a transparent, weakly scattering object, is a rapidly growing field of study. By solving the inverse scattering prob- lem, the structure of the scattering object can be reconstructed from QPI data. In the past decade, 3D optical tomographic re- construction methods based on QPI techniques to solve inverse scattering problems have made significant progress. In this re- view, we highlight a number of these advances and develop- ments. In particular, we cover in depth Fourier transform light scattering (FTLS), optical diffraction tomography (ODT), and white-light diffraction tomography (WDT).
