Compensation of aberration and speckle noise in quantitative phase imaging using lateral shifting and spiral phase integration
Inhyeok Choi, Kyeoreh Lee, YongKeun Park
We present a simple and effective method to eliminate system aberrations and speckle noise in quantitative phase imaging. Using spiral integration, complete information about syste…
Time-multiplexed structured illumination using a DMD for optical diffraction tomography
Kyeoreh Lee, Kyoohyun Kim, Geon Kim +2
We present a novel illumination control technique for optical diffraction tomography (ODT). Various spatial frequencies of beam illumination were controlled by displaying time-aver…
Three-dimensional label-free imaging and quantification of lipid droplets in live hepatocytes
Kyoohyun Kim, SeoEun Lee, Jonghee Yoon +3
Lipid droplets (LDs) are subcellular organelles with important roles in lipid storage and metabolism and involved in various diseases including cancer, obesity, and diabetes. Conve…
Holographic intravital microscopy for 2-D and 3-D imaging intact circulating blood cells in microcapillaries of live mice
Kyoohyun Kim, Kibaek Choe, Inwon Park +2
Intravital microscopy is an essential tool that reveals behaviours of live cells under conditions close to natural physiological states. So far, although various approaches for ima…
Optical diffraction tomography techniques for the study of cell pathophysiology
Kyoohyun Kim, Jonghee Yoon, Seungwoo Shin +3
Three-dimensional imaging of biological cells is crucial for the investigation of cell biology, provide valuable information to reveal the mechanisms behind pathophysiology of cell…
Quantitative Morphological and Biochemical Studies on Human Downy Hairs using 3-D Quantitative Phase Imaging
SangYun Lee, Kyoohyun Kim, Yuhyun Lee +6
This study presents the morphological and biochemical findings on human downy arm hairs using 3-D quantitative phase imaging techniques. 3-D refractive index tomograms and high-res…
