Recording of multiple holograms in photopolymer films.
Multiple images were recorded in DuPont HRF-150 photopolymer as transmission holograms by using angle multiplexing. Agreement with Kogelnik's two-wave diffraction theory for phase gratings, the time considerations and its effect on dynamic range, the necessity of a pre-illumination pulse, and good image quality at readout are reported.
متن کاملDetermination of threshold exposure and intensity for recording holograms in thick green-sensitive acrylamide-based photopolymer.
For optical data storage applications, it is essential to determine the lowest intensity (also known as threshold intensity) below or at which no data page or grating can be recorded in the photosensitive material, as this in turn determines the data capacity of the material. Here, experiments were carried out to determine the threshold intensity below which the formation of a simple hologram--...
متن کاملMultiplexing holograms for data page storage as a holographic memory in a PVA/AA photopolymer [6912-39]
Holographic data pages were multiplexed in a PVA/acrylamide photopolymer layer. This material is formed of acrylamide photopolymers which are considered interesting materials for recording holographic memories. A liquid crystal device was used to modify the object beam and store the data pages in the material. Objects with different pixel size have been used to simulate the data pages. A perist...
متن کاملPeristrophic multiplexed holograms recorded in a low toxicity photopolymer
Multiplexed diffraction gratings were recorded in 300 μm thick layers of biophotopol photopolymer by using two peristrophic multiplexing schemes separately and in combination. In addition, it was shown that riboflavin may be used as polymer initiator in acrylamide photopolymer films and the holographic properties of these films such as diffraction efficiency and dynamic range were compared with...
متن کاملMultiplexing holograms in LiNbO3:Fe:Mn crystals.
Persistent holograms are recorded with red light in lithium niobate crystals doped with manganese and iron. Different erasure mechanisms are investigated, and a recording schedule for multiplexing holograms with equal diffraction efficiencies is proposed. To test the recording schedule experimentally, we multiplex 50 plane-wave holograms with the proposed recording schedule.
