Abstract

The invention belongs to the technical field of underwater wireless optical communication, and discloses a collimation optical path design method for increasing the working distance of an underwater wireless optical communication system, which is suitable for a system of which a light transmitting end and a light detecting end both adopt an array form. Theoretical analysis is firstly carried out on a collimation light path, then light path simulation is carried out in software, and finally verification is carried out in an optical communication system. Results show that the designed optical lens group has good collimation and collection effects on optical signals transmitted in the system, solves the problem of non-uniform illumination of light spots on a detection surface caused by mutual conjugation of light emission and light detection ends in a traditional optical path collimation method, and effectively improves the utilization rate of optical power. And the working distance of the system is prolonged.

Description

technical field [0001] The invention relates to the technical field of underwater wireless optical communication, and a coaxial lens group is designed for optical path collimation to prolong the working distance of the underwater wireless optical communication system adopting an array form of light emission and light reception. Background technique [0002] The exploration and development of marine resources has a profound impact on the future development of mankind. In recent years, all countries are increasing their efforts in the development of marine resources, and various marine observation equipment has been developed and put into the ocean for use. Because equipment and base stations, equipment and equipment need to establish communication links to transmit instructions and data, and the traditional cable communication method has brought many restrictions to the use of underwater equipment, so the current demand for underwater wireless communication is also increasing...
