Abstract: 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.
