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…
Tomographic active optical trapping of arbitrarily shaped objects by exploiting 3-D refractive index maps
Kyoohyun Kim, YongKeun Park
Optical trapping can be used to manipulate the three-dimensional (3-D) motion of spherical particles based on the simple prediction of optical forces and the responding motion of s…
The effects of spatiotemporal coherence on interferometric imaging
Seungwoo Shin, Kyoohyun Kim, KyeoReh Lee +2
Illumination coherence plays a major role in various imaging systems, from microscopy, metrology, digital holography, optical coherence tomography, to ultrasound imaging. Here, we…
Universal sensitivity of speckle intensity correlations to wavefront change in light diffusers
KyungDuk Kim, HyeonSeung Yu, KyeoReh Lee +1
Here, we present a concept based on the realization that a complex medium can be used as a simple interferometer. Changes in the wavefront of an incident coherent beam can be retri…
Collaborative effects of wavefront shaping and optical clearing agent in optical coherence tomography
Hyeonseung Yu, Peter Lee, YoungJu Jo +4
We demonstrate that simultaneous application of optical clearing agents (OCAs) and complex wavefront shaping in optical coherence tomography (OCT) can provide significant enhanceme…
