High-throughput high-dynamic range imaging by spatiotemporally structured illumination
Autor: Taeseong Woo, Hye Yun Kim, Su Yeon Kim, Byungjae Hwang, Cheolwoo Ahn, Seok-Kyu Kwon, Jae-Ick Kim, Jung-Hoon Park
Publikováno v: APL Photonics, Vol 7, Iss 10, Pp 106106-106106-11 (2022)
Recent advances in biochemistry and optics have enabled observation of the faintest signals from even single molecules. However, although biological samples can have varying degrees of fluorescence expression ranging from a single to thousands of flu

Confocal Single-Pixel Imaging
Autor: Cheolwoo Ahn, Jung-Hoon Park
Publikováno v: Photonics, Vol 10, Iss 6, p 687 (2023)
Obtaining depth-selective images requires gating procedures such as spatial, nonlinear, or coherence gating to differentiate light originating from different depths of the volume of interest. Nonlinear gating requires pulsed excitation sources and ex

Overcoming the penetration depth limit in optical microscopy: Adaptive optics and wavefront shaping
Autor: Cheolwoo Ahn, Byungjae Hwang, Kibum Nam, Hyungwon Jin, Taeseong Woo, Jung-Hoon Park
Publikováno v: Journal of Innovative Optical Health Sciences, Vol 12, Iss 4, Pp 1930002-1-1930002-18 (2019)
Despite the unique advantages of optical microscopy for molecular specific high resolution imaging of living structure in both space and time, current applications are mostly limited to research settings. This is due to the aberrations and multiple s

High dynamic range imaging using a DMD
Autor: Jae-Ick Kim, Hye Yun Kim, Jung-Hoon Park, Su Yeon Kim, Seok-Kyu Kwon, Taeseong Woo, Byungjae Hwang, Cheolwoo Ahn
Publikováno v: 2021 IEEE Photonics Conference (IPC).
In many biological systems, the sample's morphological information cannot be perfectly captured simultaneously by a single image acquisition due to the limited dynamic range of the detector. Here, we propose a high throughput imaging method combined

Imaging through random media using coherent averaging
Autor: Byungjae Hwang, Taeseong Woo, Cheolwoo Ahn, Jung‐Hoon Park
We propose and demonstrate a new phase retrieval method for imaging through random media. Although methods to recover the Fourier amplitude through random distortions are well established, recovery of the Fourier phase has been a more difficult probl
