Abstract
Photoacoustic microscopy (PAM), as a novel imaging modality rapidly emerged and significantly advanced over the past two decades, offers high spatial resolution, high contrast based on endogenous optical absorption, and three-dimensional imaging capabilities. Consequently, it has been widely applied in biomedical imaging and nondestructive testing. However, conventional PAM systems face challenges in meeting the demands of real-time monitoring over large fields of view (FOV) due to limitations in imaging speed. Furthermore, their reliance on ultrasonic coupling agents restricts their application scenarios. To address the two challenges, this dissertation focuses on two primary directions for improving conventional PAM systems: enhancing the scanning speed and exploring novel non-contact PAM modalities. In this dissertation, three novel PAM systems were developed, achieving a 10- to 100-fold increase in scanning speed. Additionally, a new photoacoustic remote sensing (PARS) scanning mode that operates without the need for ultrasonic coupling agents was explored, significantly broadening the application potential of PAM in biomedicine and industrial nondestructive testing (NDT).
Biography
Xingye Tang, a doctoral candidate at the Global College, Shanghai Jiao Tong University, completed both his undergraduate and doctoral studies at the same institution under the supervision of Prof. Sung-Liang Chen. During his PhD study, Xingye Tang has published three papers as first author or co-first author in SCI journals, focusing on photoacoustic imaging. His research primarily centers on advancing traditional photoacoustic systems, with a dual focus on improving scanning speed and exploring novel non-contact photoacoustic imaging modalities.
