摘要
空间调制干涉成像 (傅里叶变换 )光谱仪 (SMIFTS)是一种有重要的研究和应用价值的空间遥感器。该文介绍了研制的Sagnac型干涉成像 (傅里叶变换 )光谱仪原理样机及用该样机进行的外场干涉成像光谱实验。实验获取了可见光、近红外谱段干涉成像图像。对其中各像元的干涉图进行数据处理和计算 。
Spatially Modulation Imaging Fourier Transform Spectrometer(SMIFTS) is an important space remote sensor for research and application. In this paper, a prototype of IFTS based on Sagnac interferometer is introduced. The field Fourier Transform spectral imaging experiment is carried out with the prototype and Fourier Transform image in visible and near infrared(VNIR) region is obtained. By processing and Fourier Transforming interferogram of each pixel, spectral image and pixel spectra is extracted with distinct spctral character.
