Recently, a new theory named compressive sensing brings revolutionary breakthrough to data collection technology and has been studied widely by researchers. The compressive sensing theory only takes in the sparse signals and reconstructs the original signal with the sparse observation. Based on compressive sensing theory, a DMD digital micro-mirror together with a single pixel detector, instead of the traditional CCD, is used for digital imaging. The novel imaging system serves as a promising model for the design of other spectral imaging systems.%近年来,一种新兴的压缩传感理论为数据采集技术带来了革命性的突破,得到了研究人员的广泛关注.该方法通过对稀疏信号进行观测,只需少量观测点就能精确的重构原始信号.基于压缩传感理论,采用DMD数字微镜结合单点探测器,而非传统CCD,进行数字成像,突破了传统数字成像系统的设计,建立了新型的成像系统.为其它光谱成像系统的设计,提供了有益的借鉴.
