| Abstract: | A new kind of method of multi-channel acquisition of thermal radiation spectra and temperature calculating was reported in this paper. Employing a tungsten lamp as thermal source, using an optical multi-channel analyzer(OMA) to collect the radiation spectra, the measured temperatures were calculated by using optimum simulation between the measured spectra and Planck black body radiation curves at the determine temperatures according to the minimum errors principle.The results are agreement with standard values, and the errors are near 1%. The advancing of the method is discussed. |
