High-resolution ultrasonic spectroscopy (HR-US) is a new technique for material analysis. This is based on the measurements of velocity and attenuation on acoustical waves at high ultrasonic frequencies propagating through materials. Optical transparency is not required because ultrasonic waves propagate through opaque systems, thereby making the technique relevant for non-transparent as well as transparent samples. In all cases, the technique provides a fast and non-destructive analysis of samples. HR-US ultrasonic spectrometers can be used in a variety of segments, including the polymers, paints and coatings industry, for an equally versatile range of tests. A number of applications are shown in the following.
