This paper presents an automated system for the evaluation and visualization of structural vibrations on the surface of solid materials in an ultrasonic frequency range using a single head laser Doppler vibrometer. For this method, the vibrometer performs a continuous scan of the surface driven by a two-axes robotic system. Scan and measurement parameters can be adapted to the requirements of geometry, frequency and resolution. Data processing techniques are employed to improve the signal-to-noise ratio and minimize the effect of inconvenient laser beam reflections caused by speckles.
