High-contrast real-time optoacoustic imaging of subcutaneous blood vessels [PDF]

, 2022
S.352-355In optoacoustic imaging, acoustical signals are generated when short light pulses are absorbed in tissue. Thus, the higher the absorption coefficient of the investigated tissue is, the stronger the optoacoustic signals will be. The absorption of

Ultrafast Optoacoustics Reveals Intricate 3D Anisotropic Elasticity in Nanocrystalline Membranes

Advanced Science, EarlyView.
Ultrafast optoacoustic spectroscopy combined with a Sagnac interferometer enables non‐contact, simultaneous characterization of thickness and the full three‐dimensional anisotropic elastic constants in freestanding nanocrystalline copper membranes. By capturing gigahertz Lamb waves and zero‐group‐velocity resonances followed by SAFE‐GA inversion, the ...
