In ITER, divertor IR thermography for measurement of surface temperature on divertor plates with high resolutions in both time and space has been designed by Japan. One of the issues is in-situ calibration of emissivity in IR light on the divertor plates, because the emissivity will change due to changes in surface properties caused by depositions and erosions. However, the in-situ calibration method has not been established yet. We recently conceived a new calibration method that an IR laser (quantum cascade laser) is irradiated to an observation surface and the emissivity will be evaluated from the scatter light. Therefore, laboratory experiments for development of calibration methods have been performed by using the components such as IR camera, heater, IR laser, black body source.
