Digital holography in optics labworks

Paper Abstract

The paper describes the digital holography experimental bench we used in our engineering school and the results we can acheived for two kind of measures:
    1. displacements on the surface of a little plate which can be deformed by a PZT actuator,
    2. amplitude of the vibrations when the PZT is excited by a sinusoidal signal.
This experiment bench have also been used for vibration mode analysis of an electrical motor in collaboration with a research laboratory. It is a very useful experiment to teach techniques using coherent light, and also features of numerical acquisition of images.
