Abstract

Ultraviolet communication, as a new type of communication, has the advantages of strong anti-interference ability, non-line-of-sight(NLOS), and all-weather operation, so it has been emphasized and become one of the research focuses in the field of wireless communication. And the light source beam angle directly determines the distance and performance of communication, but most of the current studies are limited to simulation to analyze the influence of the beam angle. In this paper, in order to verify the effect of light source beam angle on the performance of line-of-sight(LOS) and NLOS communication systems, four types of collimator lenses for controlling the light source beam angle are designed and molded, and comparative analyses of simulations and measurements are carried out. The result shows that in LOS communication, the smaller the beam angle is, the better the system performance is. In NLOS communication, the change of beam angle has less change on the path loss and almost no effect on the system performance. The conclusion are of guiding significance in promoting the practical application of ultraviolet communication.
