Abstract: In this paper，a single-pixel imaging system based on Raspberry Pi is proposed. The

proposed sys- tem 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 intro- duced in

detail from the aspects of hardware and software. Finally，the experimental results of Hadamard and

Fou- rier single-pixel imaging are shown. This work provids a new idea for carrying out optical

information processing ex- periments.
