Zusammenfassung:A multichannel adaptive interferometer based on dynamic reflecting holograms multiplexing in a photorefractive crystal of cubic symmetry is proposed. The efficiency of hologram multiplexing is studied theoretically and experimentally. For the recording geometry used, a crosstalk between channels is shown to be less than the single-channel inherent noise for a wide angular range of beams entering the crystal, and the sensitivity depletion in one channel is insignificant for a large number of channels.
