通过分析全息存储动态机制的理论模型得出，晶体中的热固定效果与晶体的氧化还原状态有关，不同氧化还原处理的晶体中进行热固定将会有不同的显影效率和固定寿命、在不同氧化还原处理的Ｆｅ：ＬｉＮｂＯ_3晶体中进行了全息存储热固定实验，记录了全息光栅的记录、离子补偿和衰减过程。实验结果与理论分析达到了很好的一致。本文作者的研究论证了氧化还原处理可以改进晶体的热固定效果，为延长晶体中固定全息图的帮助，提高固定效率，提供了一条新的途径。 By analyzing the theoretical model of the holographic storage dynamic mechanism, it is concluded that the heat-fixing effect in the crystal is related to the redox state of the crystal, and the heat-setting in different redox-treated crystals will have different developing efficiencies and fixed lifetimes. In the Fe: LiNbO_3 crystal, the holographic storage and heat-setting experiment was carried out, and the recording, ion compensation and attenuation of the holographic grating were recorded. The experimental results and theoretical analysis reached a very good agreement. The author’s research demonstrates that redox treatment can improve the heat-setting effect of crystal, and provides a new way to extend the fixation hologram and improve the fixing efficiency.
