Description

In this paper we describe a contacting shear wave array which we have used to characterize flaws in aluminum samples. By using shear waves instead of longitudinal waves, this array has doubled the resolution of our real-time synthetic aperture imaging system. The images we have obtained are significantly better than those obtained with longitudinal or surface wave arrays.

A Shear Wave Transducer Array for Real-Time Imaging
