Abstract:The present paper establishes the optimization criteria for achieving the optimum measurements in three-band pyrometry under the assumption of linear emissivity model and the sensor design with Gaussian distribution. By varying the FWHM of Gaussian distribution, the optimization analysis is investigated with the choice of the wavelength bandwidth in three-band pyrometry. For specific cases, the simulation results present the optimum bandwidth distribution. Therefore, the discussions in this paper will provide significant theoretical instructions for the design of radiation pyrometer.
