光信息存储是目前数字化信息存储的主要手段，传统二维光信息存储中存在的不足限制了存储密度及存储容量的进一步提高。基于光致漂白材料的三维光信息存储机理，建立了共焦/双光子扫描荧光显微镜系统。采用一种新型光致漂白芴类衍生物ATFTBAr作为存储材料，利用飞秒激光实现了在该材料上的三维光信息存储和读取。存储层达到四层，每层间距和信息点间距分别达到了10μm 和8μm。对信息点进行了信号强度的识别和对比，详细分析了由于折射率失配所引起的信号串扰问题。研究表明，建立的实验系统和选用的存储材料能够较好地实现三维光信息存储。

Optical information storage is the main method of digital information storage. The storage density and the possibility to further improve storage capacity were limited for the deficiencies existing in the conventional two-dimensional optical information storage. The confocal/two-photon fluorescence scanning microscope system was constructed based on the three-dimensional optical information storage mechanism on the photobleaching material. Three-dimensional optical information storage and retrieval were achieved by means of femtosecond laser on a new photobleaching ATFTBAr fluorene derivative as a storage material. The storage reached four layers and each layer spacing and information point spacing were respectively up to 10μm and 8μm. The signal intensity of the information point was identified and contrasted, and a detailed analysis of the refractive index mismatch caused by a signal crosstalk was made. Research shows that the experimental system and the establishment of the storage material can be used to achieve better three-dimensional optical information storage.
