Optical visualization of acoustic fields: the schlieren technique, the Fresnel method and the photoelastic method applied to ultrasonic transducers

K. Yamamoto,     Kansai University, Japan

Abstract:

This chapter discusses three types of optical visualization techniques for evaluating the acoustic field transmitted from ultrasonic transducers: the schlieren technique, the Fresnel method and the photoelastic method. We begin with a review of the physical mechanism of the acousto-optic interaction used in visualization techniques, and then discuss the experimental apparatus and the observed images.
