摘要
由于采用了基于菲涅耳双反射镜的干涉结构 ,使傅里叶变换成像光谱仪获得了从最高截止波数到远红外波段的很大的带宽范围。根据干涉图信号的对称性以及系统的带宽特点 ,对采集到的干涉数据进行了对称性处理 。
Because of its all-reflective layout based on the Fresnel double mirror interference system,the newly developed Fourier transform imaging spectrometer has a very large spectral bandwidth ranged from a cut-off wavelength to far infrared.In this paper,according to the signal's symmetry and wide-band characteristics,a simple method that can efficiently weaken the low frequency noise on the reconstructed spectrum is presented.
