Laser ultrasonics

Cell Imaging Using Picosecond Ultrasonics We have been developing an instrument for imaging the acoustic properties of living cells using high frequency ultrasound. We have taken the first images of living cells using the picosecond laser ultrasound technique PLU cardiacBrill.png
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 Spatially Resolved Acoustic Spectroscopy, it is a technique for mapping the surface acoustic wave velocity of a material. SRAS 300dpi sras austenitic ss.png
Cheap Optical Transducers This is a new breed of ultrasonic transducers that are activated and read optically. CHOTs offer a range of advantages over the traditional contact transducers: remote, reliable, couplant free operation with low impact on the inspected structure, activated by light and eliminating the need of wires.

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
NDE for AM We are developing technologies for additive manufacturing to enable online inspection to montior material properties and presence of defects while the part is being constructed. AMTi-150Wx5.png
Fibre optical LU We are developing a number of optical fibre based laser ultrasound systems for a variety of applications, from inspection of aerospace componets to biomedical applications. 100px
Nanoparticle acoustic transducers We are developing spherical acoustic transducers operating at the nanoscale with frequencies in the gigahertz range and with wavelengths smaller than those of visible light. TEM core shell.png
