分析了傅里叶变换红外光谱仪中动镜倾斜、机械振动等不良因素对光谱仪性能的影响。针对这些影响因素,在傅里叶变换红外光谱仪上采用定镜动态校准技术,并对光谱仪的关键性能指标参数进行了测试。实验结果表明,该仪器各项性能指标良好,该研究对光谱仪的设计和研制具有较好的借鉴意义。

The influence of adverse factors such as tilting of the movable mirror and mechanical vibration in the Fourier transform infrared spectrometer on the performance of the spectrometer is analyzed. Aiming at these influencing factors, a dynamic calibration technology with fixed mirror is used on the Fourier transform infrared spectrometer. Based on this technology, the key performance index parameters of the spectrometer are tested. Experimental results show that the performance indexes are good, which has a good reference for the design and development of the spectrometer.
