在光反馈式腔衰荡光谱技术中,光谱数据的处理因一种特殊的光谱纹波现象而变得困难。以6590.8~6591.6 cm-1光谱范围内水汽分子的光反馈式腔衰荡光谱为基础,根据光谱纹波效应的特性分析结果,提出了一种简单的数据处理方法。利用该方法确定了6590.871 cm-1处水汽分子吸收谱线的线宽约为0.1003 cm-1,这与 Hitran数据库提供的线宽结果仅有0.002 cm-1的误差,充分验证了该方法的有效性。

In optical-feedback cavity ring-down spectroscopy (OF-CRDS),the data processing of the measured spectrum is often a troubling problem for a special spectral phenomenon called spectral ripple.With an OF-CRDS example of H2 O molecule in the spectral range of 6 590.8-6 591.6 cm-1 ,a data processing meth-od based on the characteristics analyses of spectral ripple is demonstrated.The linewidth of the H2 O molecule at 6 590.871 cm-1 is determined as about 0.100 3 cm-1 with this method and its difference compared to the cal-culated result from Hitran database is 0.002 cm-1 ,which verifies the effectiveness of this method.
