中文摘要：

为了避免光谱成像系统的时间损失,提高系统光通量,提出一种压缩采样光谱调制技术,搭建了基于数字微镜器件的压缩采样多光谱成像系统.该技术基于压缩采样理论,采用编码孔径光学系统以低于奈奎斯特频率对光信息进行采样,大幅度地减少了光谱数据量.实验中根据探测器得到的隐含光谱信息的二维图像,采用双收缩快速迭代算法重建612nm激光和彩条布的数据立方体,结果表明：压缩采样多光谱成像系统不仅具有高光通量和高分辨率等特点,并在获取谱信息的同时对其进行瞬时压缩,压缩比可达31∶1.

英文摘要：

The compressive sampling spectral modulated technique is developed in order to avoid time penalty and promote throughput of spectral imaging system,and a digital-micromirror-device based compressive sampling multispectral imaging system is designed.In the technique based compressive sampling spectral information is sampled below Nyquist-criterion with coded aperture to reduce spectral data greatly.In the experiment,the cubic spatial/spectral data cubes of the 612 nm laser and colored striped fabric are reconstructed from 2-Dimension images obtained from detector that contain spectral information using double shrinkage fast iterative algorithm.The results indicate that a digital-micromirror-device based compressive sampling multispectral imaging system has images with high-throughput and high resolution,can compress the spectral simultaneously,and the compression ratio can reach 31∶1.
