摘要
阐述了电子俘获光存储技术原理 ,进行了图像写 /读 /擦除及图像加 /减等实验 ,探讨了电子俘获光存储中的动力学机制 ,研究了电子俘获材料中读出光、写入光和发射光三者之间的关系。实验表明 ,电子俘获材料以其写 /读 /擦速度快、存储密度高以及无限的读写循环寿命等优点 ,在光存储、光信息处理领域具有非常广阔的应用前景。
The optical storage mechanism is analyzed in detail according to the energy-level structure of electron-trapping material. Based on a series of experiments on writing/reading/erasing and addition/subtraction of images, the optical storage dynamics of electron-trapping material is discussed. The dependence of intensity on the emission light, stimulation light and excitation light of electron-trapping material is investigated. It is shown that electron-trapping material has such attractive advantages as high speed, high density and long life time, which will ensure a brighter future for its application in optical data storage and optical information processing.
