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.

Developing neural networks to rapidly map crystallographic orientation using laser ultrasound measurements (2024)
Journal Article
Patel, R., Li, W., Smith, R. J., & Clark, M. (2025). Developing neural networks to rapidly map crystallographic orientation using laser ultrasound measurements. Scripta Materialia, 256, Article 116415. https://doi.org/10.1016/j.scriptamat.2024.116415

Rapid measurement of crystal orientation is critical in the materials discovery process as it facilitates real-time decision-making and quality control. Acoustic inspection methods rapidly characterise microstructure without the need for extensive in...

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.

Real-time embedded pressure and flow rate sensor in polydimethylsiloxane-based microchannel using fiber Bragg grating technique (2024)
Journal Article
Zhang, Z., Hou, T., Ren, Y., Wang, C., Wang, Z., Pan, H., Li, P., Smith, R., & Wang, J. (2024). Real-time embedded pressure and flow rate sensor in polydimethylsiloxane-based microchannel using fiber Bragg grating technique. Flow Measurement and Instrumentation, 96, Article 102551. https://doi.org/10.1016/j.flowmeasinst.2024.102551

Polydimethylsiloxane (PDMS) has attracted huge interest as the soft material for microchannel fabrication, due to its high biocompatibility, durability and low cost. The rheological properties of the fluid and the deformable properties of PDMS substr...
