A procedure to monitor the critical aspects of the sampling in the authenticity tests by TL

This work addresses a contribution to specific objectives of a wide research project aimed at making operator-independent and at having an automatic system during the collection phase in authenticity test by Thermoluminescence. Here we dealt with critical aspects of the sampling regard the temperature monitoring during the drilling. A homemade system is built up to carry out the experiments and allow assessing correlation between the temperatures evaluated by elaboration of thermal images and the values of force measured from 5N to 30N in correspondence of hole generated in the brick and of the drill bit.
