Abstract

Based on dual-disperser coded aperture snapshot spectral imaging(DD-CASSI)system, method using multiple sample image (Multi Frame-DD-CASSI ) was put forward to increase the sampling rate. And a new math model was put forward to realize spectral compression in 3-D data cube. The system makes full use of spectra’s correlation, and 0.99 spectral correlation fitting and 40db image peak signal noise were achieved with 32 frames of sample images.
