交变极化改善重掺Zn：Cu：Fe：LiNbO3晶体光折变性能及体全息存储特性研究

Used Interactive Polarization Craft to Improve Zn： Cu： Fe： LiNbO3 Crystal＇s Photorefractive Properties and the Study of Volume Holographic Storage＇s Property

生长了Zn：Cu：Fe：LiNbO3晶体，对晶体进行了多次交变极化，有效的提高了Zn：Cu：Fe：LiNbO3晶体的光折变性能，使得Zn：Cu：Fe：LiNbO3晶体的响应速度大大加快，散射噪声减小，体全息存储图像质量得到较大改善。

Zn： Cu： Fe： LiNbO3 crystal has been grown. Interactive polarization craft is used, which improves the photorefractive properties of the crystals, enhances response rate, reduces scatter noise. The Zn： Cu： Fe： LiNbO3 crystal was used in volume holographic storage and the good results were obtained.
