Paper Abstract

A technique for imaging pyrometry of oxides will be presented which is capable of remotely determining the temperatures of an oxide surface with useful accuracy. The technique relies on the near-blackbody emittance properties of most oxides in the two-phonon spectral region. Most oxides in the longwave IR region are very highly emitting with an emittance that is almost temperature independent and Lambertian. We present a generalized calibration procedure for longwave cameras that allows spatially resolved surface temperature to be obtained from radiance measurements. Experimental results from a sapphire disk will be presented as a demonstration of the technique.
