PatentDOI
Tomographic phase microscopy
TL;DR: In this article, the authors present a system and methods for quantitative three-dimensional mapping of refractive index in living or non-living cells, tissues, or organisms using a phase-shifting laser interferometric microscope with variable illumination angle.
Journal ArticleDOI
Optical diffraction tomography for high resolution live cell imaging
Yongjin Sung,Wonshik Choi,Christopher Fang-Yen,Kamran Badizadegan,Ramachandra R. Dasari,Michael S. Feld +5 more
TL;DR: The quantitative refractive index map can potentially serve as an intrinsic assay to provide the molecular concentrations without the addition of exogenous agents and also to provide a method for studying the light scattering properties of single cells.
Journal ArticleDOI
Scanner-Free and Wide-Field Endoscopic Imaging by Using a Single Multimode Optical Fiber
Youngwoon Choi,Changhyeong Yoon,Moonseok Kim,Taeseok Daniel Yang,Christopher Fang-Yen,Ramachandra R. Dasari,Kyoung J. Lee,Wonshik Choi +7 more
TL;DR: In this paper, the authors proposed a method for eliminating the effect of mode dispersion and therefore realize wide-field endoscopic imaging by using only a single multimode fiber with no scanner attached to the fiber.
Journal ArticleDOI
Tomographic Phase Microscopy
Wonshik Choi,Christopher Fang-Yen,Seungeun Oh,Niyom Lue,Ramachandra R. Dasari,Michael S. Feld,Kamran Badizadegan +6 more
TL;DR: A novel tomographic microscopy for quantitative three-dimensional mapping of refractive index in live cells and tissues using a phase-shifting laser interferometric microscope with variable illumination angle is introduced.
