Abstract
Probing of the near field of an ultrasonic beam in water with a thin laser beam has verified that a diffracted beam of light, whose amplitude is a function of the angle of incident light, is related to the spatial Fourier spectrum of the far-field acoustic distribution. There are indications that this method of probing may be useful in evaluating transducer mountings. As an application of the technique, reflection-transmission properties of sound on a liquid-liquid interface are examined, and the detection of evanescent waves verifies their physical existence and properties.
