ABSTRACT
Theoretically, in high temperature measurement, the commonly used spectral range of MSP is from 0.4μm to 1.1μm in which blackbody temperature-radiation curves under dierent work-wavelengths is used to verify the method. The specific method is as follows: the Planck function calculation values of five 100°C-interval points from 2600°C to 3000°C are taken as the calibration value of source temperature range. The Planck calculation value at temperature point over 3000°C is taken as the output of MSP. Then, through NCCSP, the corresponding temperature value is obtained. Table 1 to table 3 shows the results when λ=0.4μm, λ=0.6μm, and λ=0.8μm.
