摘要： An optically stimulated luminescence (OSL) dosimeter system. An OSL reader configured to produce data indicative of a radiation exposure, one or more OSL dosimeters fabricated from a thermoluminescent material, a light stimulation source configured to stimulate the OSL dosimeter to produce luminescence emissions, and a light-detection system that measures the intensity of such luminescence emissions and converts the electrical signal to a binary string that can be processed by an appropriately programmed computer configured to analyze data from the reader and produce data indicative of an extent of radiation exposure. Dose information is obtained without requiring heating of the dosimeter. The dosimeter can be interrogated multiple times with minimal loss of dose information.

摘要： Objects are marked for identification by a luminescent label including an optically stimulable glass having trapping centers and luminescence centers. The objects are marked by exposing the luminescent label to a radiation flux to populate metastable trapping centers in the luminescent label. The labels are read by exposing the label to a second radiation flux of optical radiation, to stimulate the release of trapped charges, causing the label to luminesce. The labels may also be read without previously populating these metastable trapping centers, by stimulating prompt luminescence through exposure to a flux of UV radiation. The label is made from an optically stimulable glass, where this glass has a glass matrix with defects, where these defects may be: (i) an alkaline earth sulfide, activator Sm ions, and an additional coactivator dopant (Eu or Ce); (ii) ZnS and activator ions (Cu, Pb, Mn, Ce, Eu, Ag, Au, or Fe); or (iii) activator ions without metal sulfides.

摘要： An optical filter that uses multiple reflections to provide spectral bandpass filtering of ultraviolet, visible and infrared radiation with a very high transmission of wavelengths within a selected passband coupled with exceptional off-band rejection. The reflection filter uses dielectric-coated spherical reflectors or mirrors manufactured with absorbing glass substrates. The multiple-pass feature of the reflection filter is achieved using a traditional long-path absorption cell such as a White Cell or Wilkes Cell. The light transmitted through the reflection filter is only that light which has undergone multiple reflections as the wavelengths of high mirror reflectivity reflect off the dielectric-coated substrates. All remaining light at wavelengths corresponding to high mirror transmission is attenuated by absorption in the mirror substrate. The degree of attenuation of light at wavelengths corresponding to high mirror transmission can be chosen simply by selecting an appropriate number of reflections in the multiple-pass reflection filter.

摘要： An optically-stimulated luminescent radiation dosimeter system for the ree monitoring of radiation sources is disclosed. The system includes a radiation-sensitive optically-stimulated dosimeter which utilizes a new, doped glass material disposed at a remote location for storing energy from ionizing radiation when exposed thereto and for releasing the stored energy in the form of optically-stimulated luminescent light at a first wavelength when stimulated by exposure to light energy at a stimulating second wavelength. The system further includes: an optical source for providing stimulating light energy at the stimulating second wavelength; a photodetector for measuring optically-stimulated luminescent emissions; and an optical fiber for passing the stimulating light energy from the optical source to the optically-stimulated luminescent dosimeter to stimulate the optically-stimulated luminescent dosimeter to produce optically-stimulated luminescence light from stored energy and for passing the optically-stimulated luminescence light to the optically-stimulated luminescent detector to enable the photodetector to measure any optically-stimulated luminescent emissions occurring when the optically-stimulated luminescent dosimeter is excited by the light energy at the stimulating second wavelength. Also, the dosimeter can be used for real-time monitoring by detecting the scintillations emitted by the doped glass material upon exposure to ionizing radiation.
