摘要

在傅里叶变换光谱中,光学系统存在波畸变,对设备获得的数据影响较大。在分析傅里叶变换光谱学基本原理的基础上,给出了波形畸变干涉图的数学模型。利用该模型和计算机仿真方法,在畸变值为60nm时进行了仿真,给出了畸变的恢复谱。可见,畸变的影响会导致强度的降低和光谱细节的降低。因此,在设计和实际应用过程中,控制变形是非常重要的。

Study of the Impact of Wave Distortion in Fourier Transform Spectroscopy
In Fourier transform spectroscopy, there is a wave distortion of the optical system, and it has a greater impact on the data obtained by equipment. With analysis for the basic principle of the Fourier transform spectroscopy, we give the interferogram mathematical model of wave distortion. By using this model and the computer simulation method, we simulate with the distortion value 60nm, give the recovery spectrum of the distortion. It can be seen that the impact of distortion will lead to the decrease in intensity and the reduction of spectral details. Therefore, in the process of design and practical application, it's important to control the distortion.
