Ultrasonic Materials Characterization Laboratory

Professor: Dr. Joseph Turner

This laboratory is used for characterizing materials including metals, concrete, piezoelectrics, and ceramics. Of particular interest are diffuse ultrasonic methods for studying heterogeneous materials. Equipment in this laboratory includes two 200 MHz digital oscilloscopes, an ultrasonic pulser receiver, a 15 MHz arbitrary waveform generator, a large water tank with three-dimensional scanning control for ultrasonic measurements, preamplifiers, a large optical table with laser interferometer equipment (shown), and a variety of ultrasonic transducers (longitudinal and shear) covering frequencies from 500 kHz to 20 MHz. Computers with GPIB boards and Labview software are used for control of experiments and data acquisition.
