With the rapid increase of the number of spacecrafts, the space environment is becoming more and more complex. The demand of spacecraft for omni-directional detection of surrounding objects is becoming more and more urgent. This paper introduces a distributed space objects detection technology based on optical fiber image bundles. The system adopts multi aperture optical system. The optical signal is transmitted to the high-sensitivity image sensor through the fiber image bundle for imaging. Compared with the traditional method, the multi aperture optical system using fiber image bundles can be flexibly arranged according to the needs. The system has the advantages of wide field of view, flexible layout and low cost. This paper introduces the relevant technologies used and the principle prototype developed. © 2022 SPIE
