Abstract:Based on dual-disperser coded aperture snapshot spectralimaging(DD-CASSI)system, method using multiple sample image (MultiFrame-DD-CASSI ) was put forward, so that sampling rate was increased,and a new math model was put forward, realized spectral compression in3-D data cube. The system makes full use of spectra’s coherence, and0.99 spectral correlation fitting and 40db image peak signal noise were achieved with 32 frames sample image.
