｜主題：Applications of Diffractive Optical Elements for Biomedical Imaging
Optical microscopic techniques are most commonly used methods in biology and medical research. This talk will introduce multi-depth imaging systems, which are based on multiplexed volume holographic (MVH) gratings, acting as spatial-spectral filters used in conventional optical imaging systems. This allows the acquisition of spatial images with spectral selectivity but without scanning in both transverse and longitudinal directions. In addition, fluorescence microscopy with optical sectioning ability is extensively used in biological research and biomedicine for obtaining three-dimensional structural information of volumetric samples. With hybrid illumination, optical sectioning can be achieved in wide-field fashion. This talk will also cover multi-plane imaging, incorporating state-of-the-art nano-photonics (i.e. metasurface), to acquire optically sectioned images of volumetric tissue samples.
Yuan Luo received the MSc and PhD degrees in College of Optical Sciences in 2007 and 2008, respectively, from the University of Arizona. After post-doctoral work at 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 Institute of Medical Device and Imaging at NTU College of Medicine. He is also Program Director of Precision Medicine at NTU Graduate School of Advanced Technology, and holds the Associate Deanship in NTU YongLin Institute of Health. He has worked or held visiting appointments at the Singapore-MIT Alliance for Research and Technology (SMART) Centre in Singapore. His research interests are three-dimensional (3D) and spectral imaging, shift-invariant optics theory, design of diffractive optical elements, and implementation with 3D active structured light. He is member of the Optical Society of America (OSA)/IEEE, and has been selected as Fellow of International Society for Optical Engineering (SPIE).
