ABSTRACT:
Apparatus and method for detecting the presence of ultrasonic wave energy at a selected location within a volume of material provides a visual display indicative of the ultrasonic wave energy at the selected location, and certain characteristics of the detected ultrasonic wave energy, by coupling with the volume of material, at the selected location, a column of ultrasonic wave energy responsive fluid medium with ultrasonic wave energy responsive visible particles suspended therein so as to induce corresponding ultrasonic wave energy in the column whereby the particles are suspended in the column and are arranged in a visible pattern to establish the visual display indicative of the ultrasonic wave energy at the selected location.
