Abstract:
1. An optically stimulated luminescent (OSL) dosimeter system, comprising: an OSL dosimeter comprising a thermoluminescent phosphor material; an optical stimulation light source configured to provide a beam of optical stimulation light having a wavelength between 600 and 1100 nm to the OSL dosimeter; and an OSL reader, the OSL reader comprising: wherein the filtered optical stimulation light illuminates the thermoluminescent phosphor material in the OSL dosimeter and causes the thermoluminescent phosphor material to produce an OSL emission as it is being stimulated by the filtered optical stimulation light, a speed of a production of the OSL emission being controllable by controlling an intensity of the optical stimulation light; and wherein the thermoluminescent phosphor material produces the OSL emission without a change in its temperature after its illumination by the filtered optical stimulation light.
