提出了一种基于拓展光谱的近红外光谱模型转移方法。该方法利用一组标准样品估计源机光谱和目标机光谱之间的差异光谱,然后利用差异光谱将其他样品的源机光谱转移为目标机光谱,从而扩充目标机光谱的数量,建立目标机的稳定建模。使用三台不同仪器的近红外光谱进行了研究,结果表明,利用少量的标准样品光谱可以将大量源机光谱转移为目标机光谱,建立目标机的模型进行准确预测。该方法对仪器的更新替换具有重要的实用意义。

A method for calibration transfer was proposed based on extended spectra of a small standard sample set between master and slave machine. By using the variance spectra, a large number of spectra measured on master machine were transferred to the spectra of slave machine, which was named extended spectra. Model of slave machine was built with the extended spectra as a calibration set. Near infrared spectra on three different instruments were investigated to validate the model. Results showed that an accurate model could be obtained with the extended spectra calculated from a small set of standard samples. The method provided a useful tool for model updating when changing the mechines in practical uses.
