Near‐infrared double‐illumination optical‐resolution photoacoustic microscopy

Published: Dec 1, 2020
Abstract
Label-free chemical bond imaging is of great importance in biology and medicine. Photoacoustic imaging at the third near-infrared windows (1600-1870 nm, nearinfrared-III) provides a stable molecular vibrational imaging tool for lipid-rich tissue owing to the first overtone transition of the C-H bond at 1.7 _m. However, lacking high-energy pulsed laser sources at 1.7 _m and the strong water absorption significantly limit the signal-to-noise ratio...
