摘　　要：本文提出了一种基于树莓派的单像素成像系统.该系统以基扫描单像素成像技术为基础,以树莓派为核心,结构简单,成本低廉,可操作性强,非常适合应用于实验教学中.本文首先给出了基扫描单像素成像的原理,然后分别从硬件和软件两个方面对系统结构进行了详细介绍,最后展示了哈达玛和傅里叶单像素成像实验结果.本工作为开展光信息处理实验提供了一个新思路.In this paper,a single-pixel imaging system based on Raspberry Pi is proposed.The proposed system takes the Raspberry Pi as the core and the base-scan single-pixel imaging technology as the basis,which has a simple structure,low cost,and strong operability.Therefore,it is very suitable for application in experimental teaching.First,the principle of the base-scan single-pixel imaging is given,and then the system structure is introduced in detail from the aspects of hardware and software.Finally,the experimental results of Hadamard and Fourier single-pixel imaging are shown.This work provids a new idea for carrying out optical information processing experiments.
