METHOD AND DEVICE FOR MEASURING THE TEMPERATURE OF AN OBJECT AND HEATING METHOD

摘要

Method for measuring the temperature of an object that is heated by means of one or more radiation sources, wherein radiation generated by the object is received in at least one radiation pick-up and wherein the radiation sources are changed at least partially in intensity at a predetermined cyclic rate of change and wherein on the basis of the change in the radiation value measured by the radiation pick-up the degree of compensation for the reflectivity and/or emissivity of the object is determined.
