Description

---

This book presents principles and applications to expand the storage space from 2-D to 3-D and even multi-D, including gray scale, color (light with different wavelength), polarization and coherence of light. These actualize the improvements of density, capacity and data transfer rate for optical data storage. Moreover, the applied implementation technologies to make mass data storage devices are described systematically. Some new mediums, which have linear absorption characteristics for different wavelength and intensity to light with high sensitivity, are introduced for multi-wavelength and multi-level optical storage. This book can serve as a useful reference for researchers, engineers, graduate and undergraduate students in material science, information science and optics.

Professor Duanyi Xu received his Bachelor degree of Optical Engineering at Tsinghua University in 1961. He now works at Optical Memory National Engineering Research Center at Tsinghua University and serves as the chief scientist of National Key Basic Research (973) project. Professor Xu began to research photonic quantum memory in early 1990s. He is one of the main founders of the optical storage technology in China. He achieved multi-wavelength and multi-level optical memory and won the National Invention Award and National Science and Technology Progress Award. He has 63 Chinese invention patents and 2 United States patents, and two of them won China Outstanding Patent Award. He has published more than 240 articles and 6 monographs, in which "Principles of optical storage systems design", "High-density optical memory", "Super density and speed optical memory" won National Merit Book Award.
