为验证CO2探测仪光学设计的合理性和可行性，采用单通道模拟样机，利用太阳光加漫反射板模式对大气光谱进行实验测试，并在实验室对单通道模拟样机进行光谱定标。利用光谱配准算法对两种方法得出的谱线位置进行匹配计算，结果表明：在吸收线深度稳定位置的配准峰值点偏差小于0.006 nm，满足算法的精度要求。此种方法不仅验证了匹配算法的有效性，也验证了光学系统设计的合理性和可行性，为以后的光谱仪设计提供了理论与实验数据。

The single-channel demonstration is adopted to validate the rationality and feasibility of CO2 detec-tor optical system.Atmosphere spectrum is tested by experiment with the mode of sun light and diffuser.The spectrum calibration of the single-channel demonstration is carried out in lab.The matching calculation of two spectral position obtained from above two ways is carried on by using spectral matching algorithm.The result shows that the absorption peak point deviation is less than 0.006 nm in the line depth stable position, which could meet accuracy requirement of algorithm.This way can not only verify the validity of the matching algo-rithm, but also the rationality and feasibility of optical system design.The research provides the theoretical and practical optical reference data for spectrometer design in the future.
