Single-shot hybrid photoacoustic-fluorescent microendoscopy through a multi-mode fiber with wavefront shaping
Sylvain Mezil, Antonio M. Caravaca-Aguirre, Edward Z. Zhang +4
We present a minimally-invasive endoscope based on a multimode fiber that combines photoacoustic and fluorescence sensing. From the measurement of a transmission matrix during a pr…
Photoacoustic fluctuation imaging: theory and application to blood flow imaging
Sergey Vilov, Guillaume Godefroy, Bastien Arnal +1
Photoacoustic fluctuation imaging, which exploits randomness in photoacoustic generation, provides enhanced images in terms of resolution and visibility, as compared to conventiona…
Theoretical and experimental study of photoacoustic excitation of silica-coated gold nanospheres in water
Genny A. Pang, Florian Poisson, Jan Laufer +2
Silica-coated gold nanoparticles are commonly employed in biomedical photoacoustic (PA) imaging applications. We investigate theoretically and experimentally the PA signal generati…
Hybrid photoacoustic/fluorescence microendoscopy through a multimode fiber using speckle illumination
Antonio M. Caravaca-Aguirre, Sakshi Singh, Simon Labouesse +3
We present an ultra-thin hybrid imaging system based on an optical multimode fiber (MMF) and an optical fiber hydrophone that combines optical resolution photoacoustic and fluoresc…
Overcoming the acoustic diffraction limit in photoacoustic imaging by localization of flowing absorbers
Sergey Vilov, Bastien Arnal, Emmanuel Bossy
The resolution of photoacoustic imaging deep inside scattering media is limited by the acoustic diffraction limit. In this work, taking inspiration from super-resolution imaging te…
Super-resolution photoacoustic imaging via flow induced absorption fluctuations
Thomas Chaigne, Bastien Arnal, Sergey Vilov +2
In deep tissue photoacoustic imaging the spatial resolution is inherently limited by the acoustic wavelength. We present an approach for surpassing the acoustic diffraction limit b…
