Abstract

A broadband hyperspectral imaging system includes a light source, a scanning translation stage, a visible light imaging spectrometer, a near-infrared imaging spectrometer, first and second attitude adjustment mechanisms and a computer. The light source, the visible light imaging spectrometer and the near-infrared imaging spectrometer are respectively arranged above the scanning translation stage. The first and second attitude adjustment mechanisms are respectively used to adjust the attitudes of the visible light and near-infrared imaging spectrometers. The computer is used to receive the hyperspectral data cubes sent by the visible light and near-infrared imaging spectrometers, and perform data fusion processing on the received hyperspectral data cubes to obtain the hyperspectral data cubes from the visible light to the near-infrared band. The invention also discloses a broadband hyperspectral imaging method. The invention can reliably acquire the data cube in the visible light to the near-infrared wavelength band with low cost.

Description

technical field [0001] The present invention relates to the technical field of imaging spectroscopy. Background technique [0002] Hyperspectral imaging technology combines spectral technology with imaging technology, and uses the nanometer spectral resolution of imaging spectrometers to simultaneously image the target in tens or hundreds of spectral bands, which can not only obtain the spatial information of the target, but also obtain the target's spatial information. Spectral information. Hyperspectral imaging technology realizes the simultaneous acquisition of ground object spatial information, radiation information, and spectral information, and has the characteristics of "integration of atlas", so it has huge application value and broad development prospects in related fields. At present, the hyperspectral imaging technology mainly adopts the push-broom imaging method, which records all the spectral information of the one-dimensional space area within the line field o...
