Abstract
Ultrasonic spectroscopy is a rapid nondestructive method of measuring droplet size distributions in concentrated emulsions in situ. The ultr asonic velocity and attenuation coefficient of an emulsion are measure d over a range of frequencies, and then multiple scattering theory is used to convert these measurements to a droplet size distribution. In this article we discuss the physical basis of ultrasonic spectroscopy, present mathematical equations for converting ultrasonic measurements to droplet size distributions, and discuss the advantages and limitat ions of the ultrasonic technique compared to other techniques.
