Optical Associative Memory Using LiNbO_3:Fe Hologram : Optical Applications
スポンサーリンク
概要
- 論文の詳細を見る
Experimental investigation is presented on an all-optical associative holographic memory with storage of more than one image using an iron-doped lithium niobate single crystal in which memories can be written, erased and rewritten without developing treatment. Several images are multiply stored in the single crystal volume hologram by sequentially changing their own corresponding reference beams. Then using an image input, an output image is read out. This output image most closely resembles the input image. Threshold processing due to the sublinear photorefractive effect in the crystal is used to single out a distinct diffracted beam from the hologram.
