Temperature Imaging Measurements With a Two Wavelength Imaging Pyrometer



J E. Craig, D Lee, R A. Parker, Frank S. Biancaniello, Stephen D. Ridder


An innovative two-wavelength, imaging pyrometer with analysis software provides a method to monitor process uniformity, improve quality and reduce cost in advanced materials processing techniques. The design has achieved high imaging quality and the system measures true surface temperatures of hot objects including surfaces with roughness or emissivity variation. The measurements were made in a material processing lab and calibration results are described. Two-wavelength measurements were found to achieve high accuracy, 1.0 % of the measured value, over the range of 1000 K to 3000 K.
