Wide-band Imaging Spectrometer


Wide-band Imaging Spectrometer


As a new generation of wide band remote sensor, Wide-band Imaging Spectrometer has wide FOV (Field of View) and combination of image and spectrum. It is a sensor that integrates visible and near infrared, short wavelength infrared and thermal infrared spectrums in one instrument in the world. It is a push-broom sensor that is channel programmable in the visible near infrared spectrums and multi-spectral detection in short wavelength and thermal infrared spectrum.

During the orbit flight, Wide-band Imaging Spectrometer is mainly aimed at medium (high) ground resolution and large-scale object monitoring. It is suitable for the study of inland lakes, land and atmosphere detection, as well as for ocean and coastal zone water color and water temperature observation.
