High spatiotemporal resolution optoacoustic sensing with photothermally induced acoustic vibrations in optical fibres
Optoacoustic sensing applications are limited by weak electrostrictive force. Here, the authors induce photothermally acoustic vibrations with a focused pulsed laser, and via scanning demonstrate sensing of acoustic impedance at 10 µm spatial resolution, allowing for visualisation of diffusion dynam...

| Sumario: | Optoacoustic sensing applications are limited by weak electrostrictive force. Here, the authors induce photothermally acoustic vibrations with a focused pulsed laser, and via scanning demonstrate sensing of acoustic impedance at 10 µm spatial resolution, allowing for visualisation of diffusion dynamics. |
