Abstract
Our previous investigation regarding liquid crystal mixtures, used as a medium for dynamic holography, has proved the influence of addition of PVK (polivinylocarbazol) layer to the LC cell structure as a sensitivity amplifier [1]. This modification was very useful for bettering the dynamic properties of these modulators. In some cases (of LC Cells) we observe some kind of memory effect - holograms written before could be observed months after writing. We decided to examine different cells to determine CL Cell construction as rewritable holographic media.
