Abstract:

The lesson presents the methods of holographic, analogic and numerical interferometry. Sensibility notions, real time, intermediate time, stroboscopic measure are presented are presented and illustrated by concrete examples. Theoretical aspects proper to each method are also detailed. The case study gets onto the study of a cantilever beam by analogical holography.
