Abstract

We describe a novel acousto-optical method for measuring the size of bubbles in an ambient fluid. The method employs optical means to determine the acoustic resonant frequency of the bubbles, and hence infer their sizes. This method obviates the need for strict optical calibration, which characterizes presently available methods for bubble-sizing. It is simple and inexpensive, produces accurate results, and may be used for determining the sizes of moving or stationary bubbles.
