Abstract: Ultrasonic bursts from two transducers were stroboscopically imaged with a Schlieren setup. A standard optical lens was used to calibrate the Schlieren images. The inverse Abel transform was used to gain the radial pressure distribution at each point when axial symmetry could be said to apply. Advantages and limitations of the technique are discussed.
