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：近年來出現的壓縮感知理論為信號處理的發展開辟了一條新的道路，它指出可壓縮或者稀疏信號的少量線性投影含有

足夠的信息來進行信號重建和信號處理，在壓縮感知理論的基礎上，一種新的單像素成像系統的發展得到了廣泛的關注，它的主
