Photoacoustic microscopy (PAM), benefiting from rich optical contrast, scalable acoustic resolution and deep penetration depth, is of great importance for the fields of biology and medicine. The introduction of new scanning devices/mechanisms and fast pulsed lasers enables high spatiotemporal resolution and compact configuration. However, limited by the size and performance of reported optical/acoustic scanners, existing PAMs are bulky, heavy, and suffer from low imaging quality/speed. In this talk, I will present a multiscale photoacoustic microscopic platform consisting of large-field-of-view PAM, portable PAM, handheld PAM and endoscopic PAM, which are capable of meeting various requirements of both fundamental and clinical studies.

报告人简介：Lei Xi received his bachelor degree from Huazhong University of Science and Technology, Wuhan, China (2007) in optics, and finished his doctoral and post-doctoral training in the Department of Biomedical Engineering at the University of Florida, Gainesville, USA, in 2012 and 2014, respectively. Then, he worked at the University of Electronic Science and Technology of China (UESTC) from 2014 to 2018 as a professor. Now, he join the Department of Biomedical Engineering at the Southern University of Science and Technology (SUSTech). He is hosting the multifunctional optical imaging lab (www.mfoil.org) in SUSTech and focusing on developing novel optical imaging techniques for different biomedical and clinical studies.
