| 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。依据应用要求和信噪比方程设计并研制了Sagnac型干涉成像（傅里叶变换）光谱仪原理样机。用该样机进行了实验室干涉成像光谱实验，获取了较为清晰的可见光、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，提取出了光谱特征明显的成像光谱图像和与被测图样光谱特征相符的像元光谱。由实测光谱辐射亮度曲线反演计算出的光谱反射曲线与标准仪器测得的图样光谱反射特性曲线进行了比较，结果表明二者对应相似。

| Abstract: | 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. |
