Laser ultrasonics
| Exotic Ultrasonics for the real world | We have developed a custom CMOS linear array detector for picosecond ultrasound measurements. Performing many measurements in parallel allows us to dramatically reduce the time it takes to perform each measurement. | 
|
| SRAS for materials characterisation | SRAS stands for Spatially Resolved Acoustic Spectroscopy, it is a technique for mapping the surface acoustic wave velocity of a material. |
