| 摘 要： | 对基于多级微反射镜的傅里叶变换红外光谱仪的衍射效应进行了计算分析,讨论了多级微反射镜宽度,衍射距离以及波长产生的衍射效应对光谱复原的影响。从模拟的结果可知,在衍射距离小于10 cm,反射面宽度大于0.5 mm的情况下,衍射效应较小,而且探索出了一种可以减小噪声的数据处理方法。文章的结论将应用于微型傅里叶变换红外光谱仪的设计、数据处理以及系统的优化。

| Abstract: | Diffraction in the Fourier-transform infrared spectrometer based on step mirrors was analyzed in the present paper, and the influence of diffraction on the spectrum reconstruction with different width of step mirrors, wavelengths and distance was also discussed. It is shown that the influence of diffraction is low when the distance is less than 10 cm and the width of mirror is more than 0.5 mm. Also, a method to reduce the noises in spectrum reconstuction is discussed in this paper. The results could be used in the design of the spectrometer and the data processing in the next step. |
