Te-yuan Chung earned his Bachelor of Science degree from National Tsing Hua University in 1993 and completed his Ph.D. in Optics at CREOL, University of Central Florida, Orlando, FL, U.S.A., in 2004. Following a one-year postdoctoral position at CREOL, he assumed the role of professor in the Department of Optics and Photonics at National Central University (NCU) in Chungli, Taiwan, starting in 2006.
In 2010, he successfully executed a technology transfer, yielding loyalty earnings of 25 million NTD, and was honored with the Outstanding Technology Transfer Prize by the National Science Council, Taiwan. Te-yuan Chung has also contributed as a committee member to various international workshops and conferences. As of 2024, he has authored 47 journal papers, over 70 conference papers, and holds 14 patents.
His research interests span three main fields. One focuses on laser technologies, encompassing laser mode control using Volume Bragg Gratings (VBG), thin disk lasers, and LiDAR. Another area of focus is imaging technologies, including polarization imaging, single-pixel cameras, photoacoustic imaging, and acoustic cameras. Lastly, his research extends to thermal analysis and management, covering lock-in thermography, LED thermal management, hyperthermia treatment, and radiation cooling.
Two lab spaces are in this research group with total area of 100 m^2. Major equipment includes three optical tables (Newport), one hood, one high power Q-switched Nd:YAG laser (Ekspla), several high power pump lasers, two microscopes (Olympus BX), optical spectral analyzer (HP), and COMSOL finite element analysis software.
The ongoing projects led by Te-yuan Chung encompass several key areas:
- Thin disk Yb:YAG laser and amplifier: Collaborating with NSYSU to develop high-doping and high-power thin disk lasers for diverse scientific and industrial applications.
- VBG (Volume Bragg Grating) recording and applications: Researching synthetic photopolymers derived from monomers and employing a two-beam interference scheme to record VBGs. These VBGs serve as crucial components in laser and optics systems for laser mode control or as notch filters for various applications.
- FMCW LiDAR (Frequency Modulated Continuous Wave Light Detection and Ranging): Developing a FMCW ranging system based on a frequency-tunable single longitudinal mode diode laser utilizing VBG as a feedback mechanism. This system aims to establish depth mapping capabilities.
- Single-pixel camera: Investigating the construction of images in domains lacking array detectors, utilizing a single detector.
- Lock-in thermography: Researching non-destructive inspection technology for detecting defects in semiconductor or aerospace materials through periodic heating mechanisms with thermal imaging.
- Polarization imaging: Leveraging liquid crystal electro-optics polarization properties to develop portable and low-cost modules for smartphones, enabling polarization imaging capabilities.
These projects represent an interdisciplinary approach to advancing technologies in laser systems, optics, imaging, and thermal analysis.
