Single-photon scanning imaging based on dual-mode control
Abstract
<p indent="0mm">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.</p>
