In-plane and out-of-plane holographic interferometry with multibeam photorefractive recordings in sillenite photorefractive crystals

Holographic Interferometry based on photorefractive crystal to measure 3D thermo-elastic distortion of composite structures and comparison with finite element models

“…This configuration has been implemented for the measurement of the Poisson coefficient of a polymer sample [5] . During the phase 1 of the study the tests have been performed with the samples in a vacuum chamber, the geometry of the two illuminations has therefore been adapted to the design of this chamber ( Figure 2).…”
