The photo-electromotive force induced by a speckle pattern vibrating with large amplitude in photorefractive CdTe:V and CdTe:Ge is experimentally studied. This technique is shown to be suitable for transversal amplitude vibration measurement as well as for material response time and associated conductivity characterization. Experiments were carried out with 532 and 1064 nm wavelength illumination over a wide vibration frequency range. The results are in good agreement with a previously reported theoretical model. The studied doped crystals exhibit peculiar different features that are described and discussed.< Réduire
