【摘要】：為確定光學(xué)腔內(nèi)高反射率鏡片的反射率隨波長的變化,分別采用不同氣體瑞利散射的差異性和已知濃度的吸收氣體對同一對高反射率鏡片的反射率隨波長變化曲線進行標(biāo)定.結(jié)果表明:高反射率鏡片在359~380nm光譜區(qū)間內(nèi)反射率曲線為0.99962~0.99990,兩種方法標(biāo)定結(jié)果的相關(guān)系數(shù)達到0.998,具有較高的一致性.用腔增強吸收光譜實驗裝置與商用氮氧化物分析儀同時對實際大氣NO2進行測量,驗證了鏡片反射率標(biāo)定的準(zhǔn)確性.
[Abstract]:In order to determine the variation of reflectivity with wavelength in optical cavity, the reflectivity curves of the same pair of high reflectivity lenses were calibrated by the difference of Rayleigh scattering of different gases and the absorption gas of known concentration. The results show that the reflectivity curve of high reflectivity lens is 0.99962U 0.99990 in the range of 359~380nm spectrum, and the correlation coefficient of the two methods is 0.998, which is consistent with each other. The accuracy of specular reflectance calibration was verified by measuring the actual atmospheric NO2 simultaneously by using the cavity enhanced absorption spectrometer and the commercial nitrogen oxide analyzer.
