Optically excited nanoscale ultrasonic transducers (2015)
Journal Article
Smith, R. J., Cota, F. P., Marques, L., Chen, X., Arca, A., Webb, K., Aylott, J. W., Somekh, M. G., & Clark, M. (2015). Optically excited nanoscale ultrasonic transducers. Journal of the Acoustical Society of America, 137(1), 219-227. https://doi.org/10.1121/1.4904487

© 2015 Acoustical Society of America. In order to work at higher ultrasonic frequencies, for instance, to increase the resolution, it is necessary to fabricate smaller and higher frequency transducers. This paper presents an ultrasonic transducer cap... Read More about Optically excited nanoscale ultrasonic transducers.

Widefield two laser interferometry (2014)
Journal Article
Patel, R., Achamfuo-Yeboah, S., Light, R. A., & Clark, M. (2014). Widefield two laser interferometry. Optics Express, 22(22), https://doi.org/10.1364/OE.22.027094

A novel system has been developed that can capture the wide- field interference pattern generated by interfering two independent and incoherent laser sources. The interferograms are captured using a custom CMOS modulated light camera (MLC) which is c... Read More about Widefield two laser interferometry.

Spatially resolved acoustic spectroscopy for rapid imaging of material microstructure and grain orientation (2014)
Journal Article
Smith, R. J., Li, W., Coulson, J., Clark, M., Somekh, M. G., & Sharples, S. D. (2014). Spatially resolved acoustic spectroscopy for rapid imaging of material microstructure and grain orientation. Measurement Science and Technology, 25(5), Article 055902. https://doi.org/10.1088/0957-0233/25/5/055902

Measuring the grain structure of aerospace materials is very important to understand their mechanical properties and in-service performance. Spatially resolved acoustic spectroscopy is an acoustic technique utilizing surface acoustic waves to map the...
