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 contains 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 reconstruct the image through samples collected by one pixel detector.Thus the number of detectors in single-pixel imaging system 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
