Accuracy improvement in peak positioning of spectrally distorted fiber Bragg grating sensors by Gaussian curve fitting

HW Lee, HJ Park, JH Lee, M Song - Applied optics, 2007 - opg.optica.org
To improve measurement accuracy of spectrally distorted fiber Bragg grating temperature
sensors, reflection profiles were curve fitted to Gaussian shapes, of which center positions …

Kinetic resolution for optically active epoxides by microbial enantioselective hydrolysis

WJ Choi, EC Huh, HJ Park, EY Lee, CY Choi - Biotechnology techniques, 1998 - Springer
Resolution of several racemic epoxides was accomplished using an epoxide hydrolase activity
of whole cells of the newly isolated Aspergillus niger. (S)-Styrene oxide, for example, was …

Linear FBG temperature sensor interrogation with Fabry-Perot ITU multi-wavelength reference

HJ Park, M Song - Sensors, 2008 - mdpi.com
The equidistantly spaced multi-passbands of a Fabry-Perot ITU filter are used as an efficient
multi-wavelength reference for fiber Bragg grating sensor demodulation. To compensate for …

Multi-branch deep fusion network-based automatic detection of weld defects using non-destructive ultrasonic test

K Kim, KS Kim, HJ Park - IEEE Access, 2023 - ieeexplore.ieee.org
This study introduces a deep learning engine designed for the non-destructive automatic
detection of defects within weld beads. A 1D waveform ultrasound signal was collected using …

Molecular characterisation and expression analysis of a fish-egg lectin in rock bream, and its response to bacterial or viral infection

…, BH Nam, JW Kim, HJ Park, JH Song, CI Park - Fish & Shellfish …, 2011 - Elsevier
A fish-egg lectin, RbFEL, was identified from rock bream (Oplegnathus fasciatus) and its
expression analysed. In both vertebrates and invertebrates, carbohydrate-binding proteins (…

Investigation of Fiber Bragg Grating temperature sensor for applications in electric power systems

JH Lee, SG Kim, HJ Park… - 2006 IEEE 8th International …, 2006 - ieeexplore.ieee.org
A reliable distributed temperature monitoring is very important for electric power systems
because a power system failure will result in an enormous loss of life and property. Fiber Bragg …

Thermal analysis of 22.9-kV crosslinked polyethylene cable joint based on partial discharge using fiber Bragg grating sensors

H Kim, S Park, C Yeo, HS Kang, HJ Park - Optical Engineering, 2021 - spiedigitallibrary.org
Thermal effects of power cables are critical factors for determining the remaining lifetime and
efficiency of power grids. Herein, we propose a fiber Bragg grating (FBG) sensor package …

Production of optically active ketoprofen by direct enzymatic esterification

HJ Park, WJ Choi, EC Huh, EY Lee, CY Choi - Journal of bioscience and …, 1999 - Elsevier
For the production of optically active ketoprofen, enzymatic resolution of racemic ketoprofen
in an organic solvent has been accomplished via enantioselective esterification. …

Fiber grating sensor interrogation using a double-pass Mach–Zehnder interferometer

HJ Park, M Song - IEEE Photonics Technology Letters, 2008 - ieeexplore.ieee.org
We propose an advanced quadrature sampling method for a fiber grating sensor
interrogation. A Mach-Zehnder interferometer output is sampled at internal triggers which are …

Liquid crystal based active wavelength filter for phase-sensitive optical time domain reflectometry

…, A Lee, S Park, CI Yeo, H Yoo, C Bae, HJ Park - Optics …, 2022 - opg.optica.org
This study proposes a liquid-crystal-based active wavelength filter for phase-sensitive optical
time domain reflectometry to mitigate the amplified spontaneous emission (ASE) noise and …
