Abstract

The transformation properties of images reconstructed by dynamic χ(2) holograms recorded with radiation of the sum frequency with the use of spherical reference waves are studied theoretically and experimentally. Notions of fields and zones of locrises as regions of localization of holographic images formed by reference and object beams of different frequencies at arbitrary frequency ratios of these beams and distances from the reference point source to the hologram are defined. The domains of the parameters of the reference source ensuring the formation of real and imaginary images are determined. The reconstruction of real images by dynamic χ(2) holograms is demonstrated.
