dc.descriptionWe report the use of the photo-electromotive force (photo-emf) effect produced by a vibrating speckle pattern of light, generated by laser radiation at 1064nm, in the volume of a photorefractive vanadium doped CdTe crystal. This effect is used to measure the sample's photocondutivity and the vibration amplitude of the pattern of light. When the vibrations are much faster than the photorefractive material reponse time the photocurrent is independent of the response time. The theoretical model predicts a maximum value for the first temporal harmonic term of the photocurrent at a fixed value for the vibration amplitude-to-speckle size ratio. This prediction was experimentally confirmed and this maximum can be used to calibrate the setup in order to facilitate practical applications. © 2008 American Institute of Physics.
