Abstract
A combined optical system for determining temperature of the surface of an object or material and its distance with respect to a predetermined reference point associated with the system includes an optical radiation source emitting optical probe radiation at a predetermined wavelength or in a predetermined wavelength range, a source control unit controlling switching of the source from an operative condition, in which it emits optical probe radiation, to an inoperative condition, in which it does not emit optical probe radiation, optical detectors acquiring scattered optical radiation and thermally emitted optical radiation from the surface of the object or material, and a processing unit determining the distance of the surface of the object/material based on scattered optical probe radiation when the source is operative, and the local temperature of the surface of the object/material on the basis of thermally emitted optical radiation when the source is inoperative.
