Automated thermoluminescence measurement using microcontroller

Abstract

A dedicated real time microcontroller thermoluminescence measurement setup has been developed to measure light intensity and temperature and to control linear heating for conducting investigations on thermoluminescent materials such as alkali halides with and without doping of impurities. This instrument system permits recording of glow curve data and enables microcontroller processing of such data to evaluate glow peak temperature and activation energy. A simple and powerful 8051 microcontroller board has been developed and, along with the necessary software for this purpose, is explained fully.
