摘要
航天高光谱载荷相比于传统的多光谱载荷,在光谱分辨率上有着巨大的提升,随着定量化遥感的发展,天基探测不仅可以对地面目标的几何信息进行采集,更可以利用高光谱数据实现大气、陆地资源、战场环境、海洋物质成份的探测,随着航天高光谱技术的不断发展,高时间分辨率的对全球气候、自然资源、水纹情形的光谱成像已成为可能。高光谱探测依据成像原理的不同,主要可以分为干涉型光谱仪、衍射型光谱仪、滤光片型光谱仪。文中针对其中应用较为广泛的光栅衍射型光谱仪、时间傅里叶变换光谱仪、空间傅里叶变换光谱仪、声光调制滤光片(AOTF)光谱仪、液晶可调谐滤光片(LCTF)光谱仪、高光谱滤光片光谱仪进行了介绍,并针对每种光谱仪的优势及存在的局限性进行了分析。
Compared with traditional multispectral load, the space hyperspectral load has a great improvement in spectral resolution. With the development of quantitative remote sensing, space-based detection can not only collect geometric information of ground targets, but also detect the material composition of atmosphere, land resources, battlefield environment and marine resources by using hyperspectral data. With the continuous development of space hyperspectral technology, it has become possible to monitor global climate, natural resources and hydrographic landforms with high temporal resolution. According to different imaging principles, hyperspectral detection can be divided into interference spectrometer, diffraction spectrometer and filter spectrometer. In this paper, grating diffraction spectrometer, time Fourier transform spectrometer, space Fourier transform spectrometer, AOTF spectrometer, LCTF spectrometer and hyperspectral filter spectrometer were introduced, and the advantages and limitations of each spectrometer were analyzed.
