| 摘要 |
This invention relates to a three-dimensional optical memory made from a fluorescent photosensitive material, and a method and device for the storage and retrieval of information on the three-dimensional optical memory. The fluorescent photosensitive material can be glass and vitroceramic, both of which exhibit both fluorescent and photosensitive properties. Both one-photon and two-photon processes can be used for writing and reading the digital information on to the three-dimensional optical memory, in conjunction with a confocal microscope. A high reading sensitivity is obtained by using fluorescence during the reading cycle.
