Prof. Yu Fu
Shenzhen University, China
Speech Title: Structural Defects
Localization using an LDV-enhanced Imaging Technology
Abstract: Vibration
measurement, particularly mode shape measurement, is
important to structural dynamic analysis and defect
localization since it can validate finite element or
analytical vibration models. Laser Doppler vibrometry
(LDV) and high-speed digital image correlation (DIC)
have become dominant methods for experimental mode shape
measurement. However, vibration-based defect
localization requires measurement with both high spatial
resolution and accuracy. Unfortunately, the resolution
of DIC is not enough to detect data anomalies caused by
structural defects. On the other hand, LDV cannot
achieve high-precision defect localization due to
limited spatial resolution. We propose a defects
localization method based on LDV-enhanced full-field
vibration signatures obtained by normal-rate cameras.
The experiment proves that the spectrum of LDV offers a
guideline to remove the noise of cameras and can
dramatically improve the vibration measurement
resolution. The data fusion results show that
reference-free defect localization on various structures
can be easily localized.

area of optical dynamic measurement and structure health
diagnostics. Dr Fu is also a Fellow member of SPIE.
Prof. Yuan Luo
National Taiwan University, Taiwan
Speech Title: Advanced Optical
Systems through Flat Optics for Biomedical Applications
Abstract: Optical imaging
techniques are the most commonly used methods in biology
and medical research. In recent years, structured light
plays vital roles to enhance resolution. In addition,
nano-photonics, the emerging optical techniques, with
unique optical capabilities to manipulate the basic
characteristics of light have received a significant
amount of interest in the field of optical microscopy
and endoscopy. This talk will introduce the latest
studies on the biomedical use of structured light, as
well as metasurfaces. The following are the topics that
will be covered: quantitative cell imaging, optical
microscopy; light sheet microscopy; and optical
endoscopy. This talk will also discuss the technological
challenges presently encountered with metasurface from
the point of view of preclinical and clinical systems.
Biodata: Yuan Luo received the MSc and PhD degrees in the College of Optical Sciences in 2007 and 2008, respectively, from the University of Arizona. After post-doctoral work at the Massachusetts Institute of Technology (MIT, 2009–2011), he joined the faculty at National Taiwan University (NTU) in 2011, where he is now Director and Professor of the Institute of Medical Device and Imaging (MDI) at NTU College of Medicine. He also serves as Program Director of Precision Health and Intelligent Medicine (PHIM) at the NTU Graduate School of Advanced Technology and holds the Associate Deanship in the NTU YongLin Institute of Health. He has worked or held visiting appointments at the Singapore-MIT Alliance for Research and Technology (SMART) Center in Singapore. His research interests are in the fields of three-dimensional (3D) and spectral imaging, shift-invariant optics theory, nanophotonics, the design of diffractive optical elements, and the implementation of 3D active structured light. He is a Fellow of the International Society for Optical Engineering (SPIE).
