Study and comparison of multibeam photorefractive recordings and photorefractive crystals stack to holographic interferometry

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

“…In order to use the four-illuminations technique with the HC camera, four holograms have to be recorded in the PRC and then readout. The recording/readout of four holograms in a PRC to perform HI has already been studied [8] .…”
