Abstract

The application provides a panoramic beacon light capture system, which relates to the field of quantum communication technology. The system includes a first beacon light capture module, a second beacon light capture module, a right-angle reflective prism and an imaging target surface. The right-angle reflective prism includes The first right-angled surface and the second right-angled surface, the first right-angled surface is used to reflect the beacon light captured by the first beacon light capture module, and the second right-angled surface is used to reflect the light captured by the second beacon light capture module Beacon light, the field of view direction of the first beacon light capture module is opposite to that of the second beacon light capture module, the beacon light field angle of the first beacon light capture module is 180 degrees, and the second beacon light capture module The field of view angle of the beacon light is 180 degrees, and the total field of view angle of the first beacon light capture module and the second beacon light capture module is 360 degrees. The technical solution of the present application can receive the beacon light emitted by the transmitter in a 360-degree panorama, and can improve the accuracy of capturing the beacon light while avoiding excessive attenuation of the energy of the beacon light.

Description

technical field [0001] The present application relates to the technical field of quantum communication, in particular to a panoramic beacon light capture system. Background technique [0002] Quantum communication technology is divided into optical fiber quantum communication and free space quantum communication due to different transmission channels. At present, the prerequisite for the construction of optical fiber quantum communication system is the need to establish optical fiber links, which limits the global development of quantum communication systems, cannot meet the communication needs of mobile end users, and cannot quickly complete the construction of communication links. The quantum communication system based on optical fiber will eventually Facing development bottlenecks, free-space quantum communication has advantages such as flexibility and dynamic networking, and is considered to be a better choice for realizing a global quantum communication network.
