本文介紹我們實驗室研製的體積全像記錄的材料,稱為PQ/PMMA,它是把9,10-PhenanthreneQuinone(PQ)摻雜於Poly(Methyl MethAcrylate)(PMMA)高分子基材中所形成的感光高分子。文中首先將說明材料的製作過程與其特性,以其可能的全像記錄機制。然後,說明這種材料的體積全像儲存各項特性,包括:光學特性、散射效應、繞射效率和所儲存全像張數之間的關係、多工記錄的曝光時程…等特性。我們並以此材料展示多工儲存的技術,把數位資料記錄於所製作的感光高分子立方塊材中並重建之。
We fabricate and experimentally characterize a volume holographic recording material: phenathrenequinone doped poly (methyl methacrylate) photopolymer. Material characteristics for holographic data storage, including optical characteristics, scattering effect, relation between diffraction efficiency and number of holograms, and exposure schedule for recording multiple holograms, are investigated. An experimental demonstration of storage of multiple digital data pages in a polymer cube is presented.
