二芳烯材料是一种性能优异的光致色变材料,具有很好的抗疲劳性能,一般能重复擦写上万次,而不损失其性能。通过体全息光栅记录实验、角度复用体全息存储实验、重复擦写及强光记弱光读等实验,对二芳烯材料在重复擦写体全息存储中的应用进行了系统研究。由于二芳烯材料具有很高的折射率调制度(Δn=1.15×10-3)、可多次重复擦写、强光记弱光读的准非易失等性能,在可重复擦写的体全息存储中具有广阔的应用前景。
Di-arylene material is a photochromic material with excellent properties, has good anti-fatigue properties, and can be repeatedly erased and rewritten tens of thousands of times without losing its performance. Through the experiments of volume holographic grating recording, angle multiplexer holographic storage, repeated erasing and strong light weakness optical reading, the applications of diarylenes in repeated erasing holographic storage are systematically studied. Due to its high refractive index modulation (Δn = 1.15 × 10-3), diarylefin materials can be repeatedly erasable and write, and the performance of quasi-non-volatile materials such as strong light and weak light reading can be improved. Body holographic storage has broad application prospects.
