Improving Photoacoustic-guided Focusing in Scattering Media by Spectrally Filtered Detection
Thomas Chaigne, Ori Katz, Jérôme Gateau +3
We experimentally and numerically study the potential of photoacoustic-guiding for light focusing through scattering samples via wavefront-shaping and iterative optimization. We ex…
Influence of nanoscale temperature rises on photoacoustic generation: discrimination between optical absorbers based on nonlinear photoacoustics at high frequency
Oliver Simandoux, Amaury Prost, Jérôme Gâteau +1
In the thermoelastic regime, photoacoustic sensing of optical absorption relies on conversion from light to acoustic energy via the coefficient of thermal expansion β. In this work…
Improving visibility in photoacoustic imaging using dynamic speckle illumination
Jérôme Gateau, Thomas Chaigne, Ori Katz +2
In high-frequency photoacoustic imaging with uniform illumination, homogeneous photo-absorbing structures may be invisible because of their large size or limited-view issues. Here…
Controlling light in scattering media noninvasively using the photo-acoustic transmission-matrix
T. Chaigne, O. Katz, A. C. Boccara +3
Optical wavefront-shaping has emerged as a powerful tool to manipulate light in strongly scattering media. It enables diffraction-limited focusing and imaging at depths where conve…
Optical-resolution photoacoustic microscopy by use of a multimode fiber
Ioannis N. Papadopoulos, Olivier Simandoux, Salma Farahi +4
We demonstrate Optical-Resolution Photoacoustic Microscopy (OR-PAM), where the optical field is focused and scanned using Digital Phase Conjugation (DPC) through a multimode fiber.…
