Measurement of the single crystal elasticity matrix of polycrystalline materials (2021)
Journal Article
Dryburgh, P., Li, W., Pieris, D., Fuentes-Domínguez, R., Patel, R., Smith, R. J., & Clark, M. (2022). Measurement of the single crystal elasticity matrix of polycrystalline materials. Acta Materialia, 225, Article 117551. https://doi.org/10.1016/j.actamat.2021.117551

Many engineering metals are polycrystalline, as such the elasticity, crystalline orientation and grain distribution are cardinal factors in determining the physical properties of the material. The grain distribution can be measured using a number of... Read More about Measurement of the single crystal elasticity matrix of polycrystalline materials.

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.

3D phonon microscopy with sub-micron axial-resolution (2021)
Journal Article
Smith, R. J., Perez-Cota, F., Marques, L., & Clark, M. (2021). 3D phonon microscopy with sub-micron axial-resolution. Scientific Reports, 11(1), Article 3301. https://doi.org/10.1038/s41598-021-82639-w

© 2021, The Author(s). Brillouin light scattering (BLS) is an emerging method for cell imaging and characterisation. It allows elasticity-related contrast, optical resolution and label-free operation. Phonon microscopy detects BLS from laser generate...

Single pixel camera methodologies for spatially resolved acoustic spectroscopy (2021)
Journal Article
Patel, R., Sharples, S. D., Clark, M., Somekh, M. G., & Li, W. (2021). Single pixel camera methodologies for spatially resolved acoustic spectroscopy. Applied Physics Letters, 118(5), Article 051102. https://doi.org/10.1063/5.0040123

Spatially resolved acoustic spectroscopy (SRAS) is a laser ultrasound technique used to determine the crystallographic orientation (i.e. microstructure) of materials through the generation and measurement of surface acoustic wave velocity on a sample...
