| Abstract: | In order to comprehend the influence of spectral response coefficients on radiation spectroscopy thermometry, the VIS (visible, 200～1 100 nm) and NIR (near-infrared, 900～1 700 nm) spectrometers were used to measure the blackbody radiation spectrums at different temperature. The spectral characteristics of high temperature blackbody radiation spectrums in different wavebands were analyzed. The appropriate response wavebands of different spectrometers were selected to measure temperature. The changes of spectral response coefficient with temperature in this optimized waveband were obtained. The influence of temperature on response coefficient was analyzed in detail. The wavelength range of temperature fitting of radiation spectroscopy and the selecting criterions of response coefficient were summarized. And the influence of selecting of wavelength and response coefficient on thermometry were analyzed. It provides the important references for improving on measurement accuracy of radiation spectroscopy thermometry. |
