ABSTRACT:
A system and method for determining the temperature of an object without physically contacting the object. The method involves reading a spectral radiation of the object over a plurality of wavelengths to obtain a set of radiation data related to a temperature of the object. A known characteristic of a black body is determined at a plurality of predetermined, different test temperatures. The spectral data and the characteristic of the black body at the various test temperatures are used to calculate a temperature of the object.
