PROCEDE ET DISPOSITIF POUR LA MESURE DE LA TEMPERATURE SANS CONTACT

摘要

The temp. of a test object is detected by a pyrometric array sensitive to different spectral ranges. The emitted radiation signals are measured when the object is and is not illuminated by an auxiliary source and are combined by a processor for providing the spectral reflection characteristics of the object. The spectral reflection characteristics are used with the signals obtained when the object is not illuminated by the auxiliary source to obtain the object temp. and the spectral emission gradient using iteration and non-linear equations. The temp. is determined using the min. of information.
