Resumen: | Holographic data storage is a new optical technology which allows an important number of bits to be stored in a recording material. In this work, holographic data pages were stored in a PVA/acrylamide photopolymer layer using a peristrophic multiplexing method. This material is formed of acrylamide photopolymers, which are considered interesting materials for recording holographic memories. A liquid crystal (LCD) device was used to modify the object beam and store the data pages in the material. This LCD was used to modulate the object beam in order to reduce the zero frequency of the Fourier Transform (FT) of the object. The scheme used to reduce this frequency was hybrid ternary modulation (HTM). |
