采用双掺杂（Ｆｅ， Ｍｎ）ｖＬｉＮｂＯ３ 晶体实现了光色效应光折变全息， 实验上着重研究了不同氧化／还原状态晶体全息存储性能， 结果表明， 只有晶体具有较高的氧化程度才能实现全息的长期存储， 与理论分析一致。
Photochromic photochromic holography has been achieved by using double-doped (Fe, Mn) vLiNbO3 crystals. The holographic storage properties of the crystals in different oxidation / reduction states have been emphatically studied. The results show that only the crystals with a high degree of oxidation can achieve holographic Long-term storage, consistent with theoretical analysis.
