摘要： A method comprising the following steps: (a) adjusting a radiation dose measurement for a fluorescent nuclear track detector based on a plurality of fluorescence contrast images for the fluorescent nuclear track detector to thereby produce a calibrated radiation dose measurement, and (b) displaying the calibrated radiation dose measurement to a user and/or saving the calibrated radiation dose measurement to a storage medium, wherein the fluorescent nuclear track detector comprises a luminescent material, wherein the radiation dose measurement is based on one or more fluorescent light measurements produced by fluorescent imaging of the fluorescent nuclear track detector using excitation light from a laser having a first wavelength, and wherein the plurality of fluorescence contrast images are produced by illuminating the fluorescent nuclear track detector with excitation light having a second wavelength.

摘要： The present invention provides a method of reading information from a luminescent data storage medium comprising Al 2 O 3 . The luminescent material is a single crystal of Al 2 O 3 comprising a first dopant of magnesium and a second dopant comprising carbon wherein the material includes at least one type of oxygen vacancy defect. The disclosure relates to 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： The invention resides in an apparatus comprising an LED light source (134) for emitting a green illumination light (132) for illuminating an optically stimulated luminescence (OSL) sensor, a photodetector (162) for detecting of green luminescent light emitted by the OSL sensor, a pulse counter for counting photon pulses generated by a photodetector based on photons of luminescent light emitted by the OSL sensor and counted by the photodetector, and a microprocessor (166) for controlling the LED light source and the photodetector and the pulse counter. The microprocessor controls when the LED light source, the photodetector and the pulse counter are switched between an on state and an off state. The pulse counter is part of the microprocessor, and the microprocessor determines a radiation dose of one type of ionizing radiation to which the OSL sensor has been exposed based on the photon pulses counted by the pulse counter.
