Abstract
A laser probe technique is used for the visualization of acoustic surface vibration fields. The sensitivity achieved exceeds that attained by other methods by more than an order of magnitude. The system can be used for measurements on acoustic resonators and surface wave acoustic devices. In addition it can form the basis of an acoustic holography system. Acoustic holograms at 50 MHz have been recorded, and optically reconstructed. The resolution obtained is close to the theoretical limit for that frequency.Keywords
