Optical Wireless Network Video Transmission

Free-space optical communication technology originated in the 70s last century, in recent years as the semiconductor technology and communication technology development, especially the universal application of optical fiber communication technology, making the technology gradually developed, developing more rapidly, the application prospect is broad. Free-space optical communication has excellent privacy, and able to solve the communications, the "last mile" bottleneck problem, for human communication of high value in use.This paper introduces the free-space optical communications technology principles and an analysis of the atmospheric channel wireless transmission for the laser impact. With reference to the relevant research results at home and abroad to study the Wireless Laser digital video transmission system to receive, transmit subsystem implementation technology, and optical antenna types and their structural features of a preliminary analysis. In accordance with the actual signal transmission process, detailing the various parts of the design process and the specific implementation, the video data to achieve the free-space optical communications. Debugging with the launch system to verify the feasibility of the system.
