ABSTRACT:
For the measurement of the temperature of a body (e.g. a melt) whose temperature is such that radiation is emitted from the body surface, a camera sighted on the body surface produces a real image from a selected area of which electronic signals are derived representative of the magnitude of a plurality (preferably three) of color components of radiation. These derived signals are subsequently processed to provide a measure of body temperature.
