摘要

应用于两栖车辆平台的无线光通信系统通信距离短,具有体积小、功耗低,不使用稳定伺服系统的要求。首先分析近红外光在海平面上传输的主要衰减,并在此基础上建立链路光功率几何衰减模型,推导出在特定条件下,接收光功率与接收光轴偏离发射光轴距离、倾斜角以及光源发散角的关系。最后,应用MATLAB进行了仿真计算,得出光通信距离为100 m、300 m和500 m的最优发散角分别为24°、8°和5°,即此发散角下接收光学系统的光功率为阈值时,可偏离光轴距离达到最大。

Abstract

Wireless optical communication applied to amphibious vehicles has some requirements such as short communication distance, small volume, installing low power consumption and having no stable servo system. In this paper, the main attenuation of near infrared in the atmosphere is analyzed firstly. Then the link optical power geometric attenuation model is established. Under the specified conditions, the relationship among the receiving laser power, deviating optical axis distance, inclining angle and divergence angle is deduced. Finally, with MATLAB, the results show that the optimal divergence angle is 24°, 8°and 5°, when the communication distance is 100 meters, 300 meters and 500 meters. It means that deviating optical axis distance is maximum when receiving power being threshold value.
