CREOL Seminar: Dr. Yi-Hsin Lin - Electrically Tunable Liquid Crystal Lenses

Monday, August 29, 2022 11 a.m. to noon

Abstract: In this talk, the electrically tunable liquid crystal (LC) lenses developed in my group are introduced. I will explain how we solved the challenges limited by the essentials in physical and chemical properties of nematic LC which benefits the ophthalmic application. The main features of LC lens we developed are continuously tunable wavefronts with adjustable aberration or Zernike coefficients, adjustable focal lengths, and the ability to adjust the optical axis of LC lenses. The LC lenses are able to function as spherical lenses, aspherical lenses, freeform optical elements, and wavefront correctors for the applications of adaptive optics. I will also introduce the applications in augmented reality using LC lenses for purpose of vision corrections and solving vergence-accommodation conflict and image registrations.

About the speaker: Prof. Yi-Hsin Lin received her BS degree in physics from National Tsing Hua University (Taiwan) in 1998, MS in Institute of Electro-Optical Engineering of National Chiao Tung University (NCTU, Taiwan) in 2000, and Ph.D. in Optics from College of Optics and Photonics: CREOL & FPCE, University of Central Florida in 2006. After graduation, she joined the Department of Photonics of NCTU as an assistant professor and promoted as a full professor in 2015. In 2021, she was promoted as distinguished professor in National Yang Ming Chiao Tong University (NYCU). She is director in Tin-Ka-Ping Photonics Center, NYCU and joint appointment professor in Department of Dentistry, NYCU. She was elected as OSA fellow in 2021 and SPIE fellow in 2022. Prof. Lin received many awards, such as Google Gift for supporting Women in Tech (2022), Innolux Best Research Award(2021), Photonic Technology Contribution Award (from Taiwan Photonic Society, 2020), Facebook Distinguished Faculty Award(2020), Google University Research Award (2018), Young Investigator Award in Photonic Engineering, (from Taiwan Photonic Society, 2015), and Glenn H. Brown Prize by International Liquid Crystal Society(2008). She also received teaching awards many times, including Tin Ka Ping Teaching Award, NCTU Teaching Award, and ECE Excellent Teaching Award. She is associate editor or in editorial board in many journals: Optics Express, Liquid Crystals Reviews, Scientific Reports, SPIE Journal of Optical Microsystems, and Frontiers in Soft Matter. All these years Prof. Lin collaborates with many international companies to develop LC photonic devices, such as Nikon(Japan), Essilor(France), Coopervision(USA), Facebook(USA) and Google(USA). The research interests of Prof. Lin are LC-based photonic devices and to explore all the possibility of photonic applications using liquid crystals.
