As an advanced technology,single-photon scanning imaging has a wide application prospect in various fields,such as space target detection,air target warning,space quantum communication,quantum information processing based on diamond holes,and optical quantum computing.However,a contradiction exists between increasing the operating distance and scanning speed of single-photon imaging systems.To resolve this issue,this article investigated single-photon scanning imaging technology based on dual-mode control and completed experimental verification.This scanning imaging system uses dual-mode control of a revolving stage and a fast reflection mirror.By precisely coordinating the transmitting view angle,receiving view angle,scanning path,and scanning speed,the operating distance and scanning speed of the single-photon scanning imaging system are simultaneously improved.Compared with traditional single-photon scanning imaging systems,the proposed system has a faster scanning speed at the same operating distance and a longer operating distance at the same scanning speed.Thus,this finding is of considerable significance in developing single-photon scanning imaging technology to provide reliable technical means for rapid scanning of distant targets in various scenarios.
