A new approach to read volume holograms at different wavelengths

Abstract A new technique to read volume holograms at wavelengths different from the wavelength of recording is reported. The loss of information due to the Bragg-condition can be strongly reduced by a proper use of spherical lenses in the read-out beam. This is demonstrated for volume phase holograms stored in LiNbO3-crystals.
