- 中文摘要: 本文中,我們提出一種能執行平移及旋轉不變聯想記憶之方法。主要之實驗裝置包括一片由電腦全像片製成之空間瀘波器,一片離軸式包含有參考圖形訊息之佛涅耳式全像片及一個鈦酸鋇晶體。光學實驗之結果顯示,在輸入具有不同方位角度之部份參考圖形時,本系統都會產生完整的原始參考圖形。本文也包括在輸入非參考圖形時之實驗結果。
- 英文摘要: A method for implementing shift- and rotational-invariant associative memory is proposed. Theexperimental setup is mainly composed of a computer generated spatial frequency filter and an off-axisFresnel hologram of the reference pattern and a BaTiO3 crystal. The optical experimental results haveshown that the original reference pattern is recovered by the partial version of it in different orientationsand positions; the experimental results of non-reference patterns as inputs are also presented.
