Abstract

A laser ultrasonics system was used to detect impact damage in samples of composite material used in the Brazilian aeronautics industry. The ultrasonic generation was accomplished with a high power Nd:YAG laser at 1064 nm and the detector was a Mach-Zehnder interferometer. The Nd:YAG laser was configured so as not to cause damage to the sample and a beam homogenizer was used to distribute the laser energy homogeneously over the optical spot cross section.
