Abstract
A method for measuring the temperature in a mold by a fiber-optic measurement method and a correspondingly designed mold. For this purpose, light waveguides, through which laser light is conducted, are arranged in grooves in the outside surface of the copper mold plate. The temperature at several measurement points along the measurement fiber is determined by a temperature detection system. In particular, the method makes it possible to achieve much greater local resolution of the temperature measurements than that achieved by thermocouples.
