An experimental demonstration of spectral imaging with measurement dimensions compressed has been performed. With the method of dual compressed sensing (CS) we derive, the spectral image of a colored object can be obtained with only a single point detector, and sub-sampling is achieved in both spatial and spectral domains. The performances of dual CS spectral imaging are analyzed, including the effects...
We report an experimental demonstration of spectral imaging with a spectrometer without any scanning. The spatial resolution is provided by spatial light modulation based on the theory of compressed sensing. Objects with both continuous and discrete spectrum are used to demonstrate the performance of our system, which shows wide-spectrum and high efficient spectral imaging ability. The spatial and...
