Abstract
There is provided a method of measuring three-dimensional distribution of ultrasonic waves which allows simple real time measurement, wherein a multiplicity of bubble-shaped elements, which are trace amounts of gas coated with an extremely thin coating, are dispersed in a liquid; an ultrasonic oscillation element is placed in the liquid to radiate ultrasonic waves; the bubble-shaped elements are collapsed by the radiation of the ultrasonic waves; and changes in the optical characteristics of the liquid caused by the collapse of the bubble-shaped elements are visually measured.
