| 摘 要： | 基于现有的DVD光头物镜与音圈电机，根据光致漂白的双光子吸收气维光信息存储原理，以钛蓝宝石飞秒脉冲激光进行双光子光信息写入和读出，利用音圈电机进行选层，在新型光致漂白材料二苯乙烯衍生物中进行光致漂白二进制编码信息的存储和读出实验研究；实现了三层光信息存储，信息点间距和信息层间距分别为4μm和15μm；用Matlab软件读出信息的信号强度并对其进行了识别，识别结果与写入的二进制编码信息完全一致。实验证明了用DVD光头进行双光子三维光数据存储的可行性，表明双光子吸收光致漂白技术可以与现有CD／DVD兼容，为实现多层高密度和超高密度光信息存储打下基础。 |

| Abstract: | Based on the objective lens and voice coil motor of the current DVD pickup head,according to photobleaching three-dimensional (3D) optical information storage's theory of two-photon absorption,the Ti∶sapphire femtosecond pulse laser was used as written optical beam and reading optical beam of two-photon three-dimensional optical storage voice coil motor was carried through multiplayer choice, and the storage and readout experimental study of binary format code with two-photon photobleaching in the new photobleaching material consisting of stilbene derivant was conducted. Three layers optical data storage was realized,the two adjacent bits distance in each layer was 4 μm and the two adjacent layers interval was 15 μm. The signal intensity of the written information was readout and identified with Matlab software,and the identified result matchesd with the written binary format code。The experiment proved that proceeding two-photon three-dimensional optical data storage with DVD pickup head was feasible, which indicated that two-photon photobleaching technology combined with the current CD/DVD and provided a base for realization of high density and super high density optical data storage. |
