Our aim is twofold: to present our temperature measurement system based on CCD technology, which gives a linear response versus temperature, and to display two industrial applications in which our system has been involved to optimize and characterize the process. We present a short summary dealing with temperature evaluations from radiation measurements. We consider especially the problems of the surroundings, the atmosphere, and the emissivity assumption. After selecting a value for the emissivity, we show that the use of the CCD technology enables us to obtain high spatial and temporal resolution temperature imaging, and provides further information, mainly a linear response versus temperature, which will enable real-time implementation. Our measurement system based on CCD technology is particulary dedicated to process control in the steel industry. CCD technology does not require a substantial cost and provides a lot of paramount information, enabling us to optimize some industrial applications based on accurate relative temperature measurements. We show, through two industrial examples, the results provided by our system and how it enables us to optimize the process involving knowledge and the control of temperature.
