Richard Smith
Electronic engineer, specialities: optics, microscopy, femtoseconds lasers, ps ultrasonics. I completed my PhD in Electrical and Electronic Engineering in 2006 at the UoN. My early work focused on optical metrology and signal processing techniques to enable precise measurements to be made below the optical diffraction limit. I have been developing several picosecond ultrasonic systems at UoN, and have successfully developed a parallel detection scheme that has increased the data acquisition rate by over an order of magnitude compared with the traditional detector approach. Current research themes are developing instrumentation to provide true orientation imaging of material microstructure in primarily aerospace materials, and developing high frequency ultrasonic transducers for biological applications
