Abstract: In principle all objects emit thermal radiation as a consequence of their temperature. The thermal radiation emitted by an object depends on its temperature, surface condition and thermal properties. A thermography camera senses the emission from object, converts into temperature and display thermal images. The thermography camera is defined as measuring instrument used for non-contact measurements of the surface temperature of objects. The thermography camera generate thermal image of an object being viewed by converting radiant heat energy from the object into a signal that can be display on a monitor. The radiant heat emitted from the object is directly proportional to its temperature. Thermal image come into view as zones of different colours or shades depending upon the temperature range and mean temperature selected. The bright regions in the thermal image indicate high temperatures and the dark regions indicate low temperatures. In this study we make use of laser heating of High Temperature High Pressure (HTHP) industrial diamond, as well as the optically measured temperature profile of the HTHP industrial diamond surface. A XenCls thermography camera was used to measure the temperature profile of the sample (HTHP industrial diamond)
