Claim Text:
1. A thermoluminescent dosimeter (TLD) system, comprising: a thermoluminescent dosimeter comprising a thermoluminescent substrate having a thin layer of light-absorbing material disposed on one surface thereof, a thickness of the thermoluminescent substrate being much greater than a thickness of the light-absorbing material; a stimulation light source configured to provide light having a wavelength of between 550 nm and 1200 nm to the thermoluminescent dosimeter; and a TLD reader, the TLD reader comprising: wherein light from the stimulation light source enters the TLD reader and is filtered by the first optical filter to form the filtered stimulation light, the filtered stimulation light striking the light-absorbing material on the thermoluminescent substrate without first traveling through the thermoluminescent substrate; wherein the light-absorbing material becomes heated from an absorption of the filtered stimulation light; wherein the thermoluminescent substrate becomes heated from an absorption of light by the light-absorbing material; and wherein the thus-heated thermoluminescent substrate produces the TL emission.
