摘要： The present invention provides methods and apparatuses for writing information to, reading information from, and erasing information on a luminescent data storage medium comprising Al 2 O 3 . The method includes writing and erasing of the information using photoionization via sequential two-photon absorption and non-destructive reading the information using one-photon absorption and confocal fluorescent detection. The apparatuses for writing and reading the information incorporate confocal detection and spherical aberration correction for multilayer volumetric fluorescent data storage. The methods also allow multilevel recording and readout of information for increased storage capacity.

摘要： There is provided a system and method for estimating radiation exposure in real time or in near-real time while a dosimeter is being irradiated. In the preferred arrangement, OSL will be used to calculate estimates of the radiation dose rate, preferably by using comparisons between illumination values measured during and after lighting the dosimeter with a laser light of a predetermined frequency. A first preferred embodiment utilizes quasi-equilibrium OSL intensity with periodic stimulation during continuous irradiation. Another preferred embodiment utilizes the amplitude of the transient OSL signal during periodic stimulation. Another preferred embodiment utilizes the difference between the OSL intensity at the end of one stimulation period and the beginning of the next. Finally, another preferred monitors the time constant for the return of the transient OSL signal to equilibrium, following either a change in dose rate or during a periodic optical stimulation.
