Laser-fiberoptic non-contact controlled heating of samples for thermoluminescence measurements

Thermoluminescence (TL) measurements are based on exciting a sample and measuring the light emitted from the sample while it is being heated. The exact heating scheme is difficult to control or to change by a standard heater. We have developed a novel laser-fiberoptic system for heating a spot on the surface of a sample and monitor the TL signal emitted from this spot. With this system it is very simple to control the heating rate (e.g. linear heating, exponential heating), to measure samples in remote locations and to measure several spots on the surface of one sample. The laser-fiberoptic system would be particularly useful for thermoluminescence dosimetry (TLD) measurements.
