中文摘要:在双色散结构的编码孔径光谱成像系统(DD-CASSI)的基础上提出了利用多帧采样图的方法(Multi Frame-DD-CASSI) ,用以提高信息采样率,并提出新的数学模型,实现了对三维数据立方体的光谱维压缩编码,充分利用了光谱维数据的相关性,利用 32 帧采样图恢复数据,达到了 0.99 的光谱曲线相似度和 40db 的图像峰值信噪比。

Multi- frame image coded aperture snapshot spectral image technology
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.
