Optoacoustic lenses for lateral sub-optical resolution elasticity imaging (2024)
Journal Article
Yao, M., Fuentes-Dominguez, R., La Cavera III, S., Perez-Cota, F., Smith, R. J., & Clark, M. (2025). Optoacoustic lenses for lateral sub-optical resolution elasticity imaging. Photoacoustics, 41, Article 100663. https://doi.org/10.1016/j.pacs.2024.100663

In this paper, we demonstrate for the first time the focusing of gigahertz coherent phonon pulses propagating in water using picosecond ultrasonics and Brillouin light scattering. We achieve this by using planar Fresnel zone plate and concave lenses... Read More about Optoacoustic lenses for lateral sub-optical resolution elasticity imaging.

Label-free Brillouin endo-microscopy for the quantitative 3D imaging of sub-micrometre biology (2024)
Journal Article
La Cavera, S., Chauhan, V. M., Hardiman, W., Yao, M., Fuentes-Domínguez, R., Setchfield, K., Abayzeed, S. A., Pérez-Cota, F., Smith, R. J., & Clark, M. (2024). Label-free Brillouin endo-microscopy for the quantitative 3D imaging of sub-micrometre biology. Communications Biology, 7(1), Article 451. https://doi.org/10.1038/s42003-024-06126-4

This report presents an optical fibre-based endo-microscopic imaging tool that simultaneously measures the topographic profile and 3D viscoelastic properties of biological specimens through the phenomenon of time-resolved Brillouin scattering. This u... Read More about Label-free Brillouin endo-microscopy for the quantitative 3D imaging of sub-micrometre biology.

Phonon imaging in 3D with a fibre probe (2021)
Journal Article
La Cavera III, S., Pérez-Cota, F., Smith, R. J., & Clark, M. (2021). Phonon imaging in 3D with a fibre probe. Light: Science and Applications, 10, Article 91. https://doi.org/10.1038/s41377-021-00532-7

We show for the first time that a single ultrasonic imaging fibre is capable of simultaneously accessing 3D spatial information and mechanical properties from microscopic objects. The novel measurement system consists of two ultrafast lasers that exc... Read More about Phonon imaging in 3D with a fibre probe.
