Distortion of the Interferometric Signal in the Fourier Transform Spectrometer
Author(s): 
Pages: 25-30
Year: Issue:  4
Journal: INFRARED TECHNOLOGY

Keyword:  傅里叶变换光谱仪干涉图相位畸变;
Abstract: 简要论述了傅里叶变换光谱仪的测量原理,详细说明了几种产生干涉信号畸变的原因,分析了它们在干涉图上的具体表现,并在计算机上仿真得到相应的畸变干涉信号.另一方面,利用一台自行研制的环境适应性相当好的傅里叶变换光谱仪,观察到了与前面所论述的畸变相接近的干涉图,从而验证了分析结论的正确性.由此可见,自行研制的傅里叶变换光谱仪尽管方案正确、性能优越,但还需要在许多方面作相应的改进.
