The article focuses on a new generation of ultrasonic equipment that could enable one to see reinforcing bars in concrete without even touching the surface. Recent developments in ultrasonic nondestructive testing for other applications have resulted in new transducer and signal processing technologies. The Ultrasonics Research Group at Warwick University is currently exploring the possibility of developing a second generation of non-destructive testing instruments for construction materials based on the new techniques. A recent grant from the Royal Society's Mercer Award scheme has been used to obtain a high-power signal generator optimized for use with construction materials.
