Use of a Microsphere Probe for Pressure Field Measurements in the Megahertz Frequency Range

Abstract

A procedure has been developed that may be used to measure the finestructure of acoustic fields at frequencies up to 10 MHz. It consists basically of locating a microsphere in the pressure field at the point of interest and measuring the amplitude of the scattered waves. Details of the system are discussed, and some examples of experimental data presented.
