Development and Spectral Imaging Experiment of Sagnac Type Imaging Fourier Transform Spectrometer(IFTS)
Sagnac型干涉成像光谱仪研制及干涉成像光谱实验

Spatial Modulation Imaging Fourier Transform Spectrometer(SMIFTS) is an important remote sensor for research and application.In this paper,based on application requirement and SNR equation,the prototype of Sagnac type IFTS is designed and manufactured.The spectral imaging experiment is carried out with the prototype in laboratory and an clear image has beer obtained in visible and near-infrared (VNIR) region .By processing and Fourier Transforming interferogram of each pixel,spectral image and pixel spectra is extracted with distinct spectral character.Comparison between the traget's spectral reflectivity curve measured by standard device lambda 9 and it's evaluated reflected spectral curve from spectral imaging experiment are carried out. The results indicate that the corresponding curves are similar.
