Abstract
Double pulse holographic interferometry (DPHI) ideally completes standard accelerometrical techniques used for dynamic analysis but has some limitations. We present in this paper the development of a new original method based on DPHI allowing the measurement of the 3-D displacement vectors field with multi-pulse recordings. The method is based on three illuminating beams and one viewing direction and multi-pulse recording is achieved by fast deflection of reference beams. Accuracy is discussed and validated in experimental dynamic conditions through the analysis of vibration modes of a sinusoidally excited cylinder.
