Ultrasonic beams radiated from a circular transducer are visualized using a Michelson interferometer. The light source of the interferometer is a 632.8 nm-He–Ne laser. The test light that passes through the radiated sound fields is interfered with by the reference light. Therefore, the index of refraction gradient including sound pressure information is transformed into the intensity of the interference light that can be electrically acquired by a photodetector. The transducer is 8 mm in diameter and its center frequency is 1.416 MHz. The visualization region is 100 mm in the sound axial direction, and $\pm 30$ mm in the lateral direction, where the origin is the center of the vibrating surface. Information acquired as a result of the experiment is the two-dimensional image that is a projection of the three-dimensional sound pressure distribution along the optical axis.
