Abstract
The spatial fidelity of amplified images in photorefractive materials due to spatial pin variations with computation and experiment based on BaTiO3 is investigated. The results will indicate how the spatial fid elity of the amplified images decreases as the relative aperture of th e Fourier transform lens used in the system increases, and varies with the angle between the pump beam and the axis of the signal converging wave.
