Abstract
A commercial infrared thermography system has been used to monitor workpiece surface temperatures during laser heat treatment. A simple optical filtering technique was used to increase the upper temperature limit of the thermography system. Experimental results are presented which demonstrate an accuracy of ±10%. The filtering technique is applicable to most commercial infrared thermographic systems.
