Abstract

Single-pixel imaging system can get image through a detector without spatial resolution. It is a lower-cost alternative to multi-pixel detectors. In addition, the single-pixel detector can provide higher performance, such as higher detection efficiency, lower noise and faster time response. However, single-pixel imaging often needs to be modulated by expensive digital micromirror device (DMD) or spatial light modulator (SLM) to produce structured light. Moreover, DMD or SLM makes the imaging system more complex and brings difficulties to integrated design. Therefore, we propose a method of replacing DMD and SLM with an arbitrary display screen (computer screen, mobile phone screen, liquid crystal display, organic light-emitting diode and so on) to realize structured light illumination. A variety of display screens with low price are widely used in the market. And it is convenient to drive and control, it has a long service life and high stability. By programming the processor, we can control the display screen to generate any desired structured light directly. We also compared the recovery effects of different algorithms. The results show that display illumination can replace DMD or SLM in single-pixel imaging system.
