Paper Abstract

Read-out of volume phase holograms in photorefractive crystals with a wavelength that is different from the wavelength of hologram formation imposes the difficulty to match the Bragg condition for all spatial frequencies of the object to be stored. Therefore, the quality of the reconstructed image decreases and resolution and image field losses are observed. Experimental and theoretical examinations of these effects reveal that the geometrical configuration of the writing experiment determines the reconstructed image field. Depending on the wavelength of read-out an appropriate reconstructing wave can be formed with the help of lenses diminishing image field and resolution losses considerably.
