  • Random grating based compressive sensing wideband hyperspectral imaging system
    Patent number: 10136078
    Abstract: A random grating based compressive sensing wideband hyperspectral imaging system comprising a front imaging component, an optical splitting component, more than two branches, and a computer, with each branch having an exit pupil transformation component and a compressive spectral imaging component. The system is based on compressive sensing theory, makes use of the correlation between spectra, increases compression rate on the spectral dimension, realizes three-dimensional compressive collection of wideband spectral image data, and greatly reduces data collection amount. The system is capable of measuring spectral image information on a wideband spectrum with a single exposure, and may obtain high spatial resolution and high spectral resolution by means of designing the random gratings on the various spitting paths.
