Paper Abstract

A technique by which ultrasonic waves are visualized is described. The method uses double- exposure holographic interferometry using iron doped lithium niobate crystals as the storage medium. These photorefractive crystals are self-developing, erasable and reusable, making them attractive for interferometry applications. This paper presents results of: (1) ultrasonic field parameters determined using the holographic method such as ultrasonic wavelength, and true resonance frequency of the transducer, (2) an example of image enhancement using image-substraction by phase modulation, and (3) initial results of visualization of ultrasonic wave fronts using a Nd:YAG laser.
