Abstract

Identification of dynamic material properties, non-destructive testing and study of vibroacoustic behaviour of different structures impose complex, pointwise and full-field measurements. Among other techniques, optical non-contact techniques are representing today the favourite choice since they do not add any mass to the structure under test. When the range of vibration amplitudes is small, most of these techniques are based on interferometric principles.
