Abstract

The possibility of using lasers for non-contact vibration measurements has been known since the mid-60s. This work describes the development of some applied areas: the use of laser vibrometry in near-field acoustic holography, verification of numerical models of vibrations of complex structures, and vibration flaw detection.
