Abstract :
A correlation method has been only recently introduced into acoustic microscopical techniques for the measurement of frequency dependence of velocity and attenuation in a small quantity of liquid. The experiments have been demonstrated with drops of water (0.1¿0.2 cm3) as a standard liquid material over the frequency range from 100 to 340 MHz. The system has been established with accuracy better than 0.2% and 3.9% for velocity and attenuation, respectively.
