摘　　要： 介绍了国外先进高光谱成像载荷发展情况和国内以高分五号载荷为代表的高光谱成像技术发展水平,凭借在光谱分辨率、空间分辨率、成像质量等方面取得的长足进步,广泛应用于资源勘探和环境监测等多个重要领域。分析了Offner结构和Dyson结构的推扫型成像仪的特点,提出未来凝视型成像方式的发展前景,并介绍了目前基于AOTF分光方法的中红外高光谱成像仪,实现了较好的光谱成像效果。 Several advanced foreign hyperspectral imaging loads,as well as the hyperspectral imagers in GF-5 are introduced,which have been widely used in resource prospecting and environment monitoring,for the great progress of spectral resolution,spatial resolution and imaging quality. The features of Offner push-broom imagers and Dyson push-broom imagers are analysed while the staring-type hyperspectral imagers are expected to play an important role in the future. A kind of MIR hyperspectral imager based on acousto-optic tunable filter（ AOTF） is introduced,which provides satisfactory spectral and spatial effect.
