Abstract ：The newly emerging compressive sensing theory in recent years has opened up a new path for the development

of signal processing.It describes that a small group of non-adaptive linear projections of a sparse or compressible signal con-

tains enough information for signal reconstruction and processing.Based on the compressive sensing theory ，the development

of a single-pixel imaging system has received extensive attention.The most intriguing feature of the system is that ，it can re-

construct the image through samples collected by one pixel detector.Thus the number of detectors in single-pixel imaging sys-

tem is much less than the number of pixels.The reconstruction algorithm for a single-pixel imaging system image based on

compressive sensing theory is mainly described.It has done a useful exploration for a single-pixel imaging system。

Key words ：signal processing ；compressive sensing ；signal reconstruction ；a single pixel imaging

摘 要：近年来出现的压缩感知理论为信号处理的发展开辟了一条新的道路，它指出可压缩或者稀疏信号的少量线性投影含有

足够的信息来进行信号重建和信号处理，在压缩感知理论的基础上，一种新的单像素成像系统的发展得到了广泛的关注，它的主

要特点就是只用一个像素的探测器通过用少于图像像素值的采样数目来重建图像，主要介绍了基于压缩感知理论的单像素成像

系统的图像重建算法，为单像素成像系统的发展做了有益的探索。
