Ground imaging spectral measurement system

The invention belongs to the fields of remote sensing technology and the spectrum technology and relates to a system that obtains spectroscopic data of surface features on the ground and preprocesses the data. The system comprises an imaging spectroscopic data obtaining module, a data collecting, storing and processing module, a drive controlling module and a multifunction system platform. Surface features are imaged through a slot vertical to the orbital direction. The light beams set off from the collimation mirror are parallel to each other. Upon penetrating a dispersion device, the light beams disperse in the direction of the vertical strips according to the light spectrum and are imaged on the photosensitive surface of the detector after penetrating the convergent mirror. Then further data processing and image display are conducted. The ground imaging spectral measurement system of the invention can obtain uninterrupted imaging spectroscopic data of the surface features with highspectral and spacial reso
