Images are among the most straightforward approaches for human to sense or to understand the world. Consequently, imaging gains a lot of attention in scientific research. Terahertz is the last spectrum to be explored, which contains numerous information of matters. Compared to classical microwave imaging, it leads to decent resolution. However, compared to optical imaging which is more popular in daily life, the resolution needs to be improved. So how to make good use of the spectrum, and how to make THz images more vivid, are important questions.

In this talk, I will introduce the work going on in THz Imaging Lab., from imaging theory (including system modeling and super-resolution approaches beyond the physical limits), key components (including self-developed THz sources and detectors, high-performance lenses), and imaging systems (including radar and cancer diagnosis). All of the contents above are from our first-hand experience.

Feng Qi got his Bachelor's degree in Zhejiang University, he did his master and PhD studies in ESAT-TELEMIC, Katholieke Universiteit Leuven, Belgium. Since 2011, he worked in RIKEN, Japan; Goethe University, Germany and University of Birmingham, UK, all on THz science and technology. In 2015, he went back to Shenyang, China and founded the THz Imaging Lab.. Now the team is working on both electronics and photonics. Feng Qi has published over 120 papers and gave 14 invited talks in both international and national conferences. He served TPC and session chairs in several international conferences like IRMMW-THz, ICC, GSMM etc.. He got the “Best Paper Award” in GSMM 2014. During the past five years, Feng Qi works as the project leader from 6 national projects, including The National Key Research and Development Program of China (four 863 and 973 programs totally).
