Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to the specific embodiments.

[0048] refer to figure 1 and figure 2 , an unmanned aerial vehicle relay laser communication system of the present invention mainly includes a double-input and double-output optical fiber amplifier, and the two ends of the optical fiber amplifier are respectively connected in turn with a three-port CWDM wavelength division multiplexer and four CCD image sensors. Device (6) and coupling lens group, four CCD image sensors are respectively located on the four quadrants of the coordinate system with the optical fiber coupling end face as the center of the circle, and the center of the light spot detection surface formed by the CCD image sensors is the coupling point. When the specific regions of the four CCDs are all When a certain light spot is detected, that is, whe...

Abstract

The invention discloses a relay laser communication system of an unmanned aerial vehicle, comprising an optical fiber amplifier, two ends of the optical fiber amplifier are respectively connected witha wavelength division multiplexer, a spot detector and a coupling lens group in turn, a scanning swing mirror is arranged on the front side of the coupling lens group, and the scanning swing mirror is connected with a servo turntable for controlling the movement of the scanning swing mirror to receive and emit signals. The relay laser communication system of the invention can greatly increase theinformation transmission distance of the ground point-to-point laser communication and make the broken line transmission link of the laser signal possible; the relay laser communication system of theunmanned aerial vehicle can greatly increase the information transmission distance of the ground point-to-point laser communication. The unmanned aerial vehicle (UAV) is utilized to reduce the requirement of the laser communication on the terrain environment, and the UAV has a long delay time and is easy to manipulate flexibly, so that the relay laser communication system of the UAV is more widely applicable.

Description

technical field [0001] The invention belongs to the technical field of wireless laser communication, and in particular relates to an unmanned aerial vehicle relay laser communication system. Background technique [0002] With the development of science and technology, the production cost of UAVs is getting lower and lower. Therefore, UAVs are characterized by no risk of casualties, strong survivability, flexible movement, not restricted by terrain factors, strong anti-interference ability and long-lasting time in the air. Long and other advantages, can be combined with professional technologies in various fields, and used in more and more fields. UAV laser communication is a kind of application of UAV in the field of communication. [0003] UAV laser communication system plays an important role in command communication in modern warfare. The laser communication link has the advantages of large communication capacity, high transmission rate, good concealment, strong anti-int...
