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. Ultrafast Camera.PNG
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. SRAS 300dpi sras austenitic ss.png

Nanoscale Ultrasonic Transducers We have created new ultrasonic transducers operating at the nanoscale with frequencies in the gigahertz range and with wavelengths smaller than those of visible light. These will enable the diagnostic power of ultrasonics to be used at the nanoscale. BNC hair2highlightred.PNG
