Abstract
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.
