Microstructure Characterization with a Pulsed Laser Ultrasonic Source

  • Chapter

Abstract

Localized heating produced by absorption from a pulsed laser provides an efficient noncontacting source of ultrasonic waves in materials. This paper describes the results of experiments conducted to illustrate the feasibility of this type of source fot microstructure characterization in metal and ceramic materials. Piezoelectric and capacitive wide bandwidth detection transducers have been used to record attenuation and scattering in these materials for comparison with the conventional pulse echo technique. The laser source was found to be art efficient, versatile, and wide bandwidth noncontacting source.
