Problems solved by technology

[0031] In strong winds or due to the shaking of the building due to earthquakes, the optical signal sent by the transmitter is not aligned with the receiver, resulting in large errors, and even communication cannot be realized
The current research direction is to improve laser aiming, how to use non-mechanical devices to achieve precise alignment and fast aiming; in terms of receivers, scattered light also carries information, the more scattered light is received, the greater the received signal energy, But at the same time, the received noise is also greater, so it is the research goal to increase the total power of the receiver received signal without reducing the signal-to-noise ratio.

Abstract

The invention relates to a laser self-adoptive trace adjustment system with simple structure and convenient use. The laser self-adoptive trace adjustment system comprises an information gun which is matched with an information target, and an adjustment gun which is matched with an adjustment target. A controller I is arranged between the adjustment gun and the adjustment target, and a controller II is arranged between the adjustment gun and the information target.

Description

technical field [0001] The invention belongs to the technical field of wireless optical access, in particular to a laser adaptive tracking adjustment system for aiming and tracking laser signal emission and reception. Background technique [0002] With the advent of the information society, communication technology has also been developing with each passing day. In the past few years, people have higher and higher requirements on the transmission rate, and the number of users who use high-speed data transmission is increasing every year. Because optical fiber communication can transmit high-speed data, it has become the backbone network of the wide area communication network. Today, more than 80% of the information in the wide area communication network is transmitted through optical fibers. But from the optical fiber backbone network to the "last mile" between users, if laying optical cables, it will not only cost a lot but also time-consuming; many wireless communication ...
