Paper Abstract

Spectral video is crucial for monitoring of dynamic scenes, reconnaissance of moving targets, observation and tracking of living cells, etc. The traditional spectral imaging methods need multiple exposures to capture a full frame spectral image, which leads to a low temporal resolution and thus lose their value as spectral video. The new code aperture snapshot spectral imaging (CASSI) method has been emerging in recent years, which is suitable for spectral video acquisition, due to its high-speed snapshot and few-amount measurements. Based on the CASSI, this paper proposes a compressive spectral video acquisition method with double-channel complementary coded aperture. The method can achieve the spectral video with a high temporal resolution by directly sampling the 3D spectral scene with 2D array sensor in only one snapshot. Furthermore, by using the double-channel complementary coded aperture in compressive measurement and the sparse regularity in the optimization recovery together, we can obtain the higher PSNR and better visual effects compared with the single-channel CASSI. Simulation results demonstrate the efficacy of the proposed method.
