Introduction
The project was to investigate ways to make high frequency ultrasonic measurements more practical and applicable to real world applications. Our approach to improve the utility of these experiments is to dramatically reduce experiment time by parallelizing the measurements. Two approaches were adopted - developing high frequency parallel camera working in the 1-10 GHZ range for real time measurement of the ultrasonic signals, and parallelization of the traditional approach of lock in detection.
Picosecond laser ultrasound is an established technique for material characterization. The frequencies involved span from ~1 - 100's of GHz. tbc.
