Smart License Plate in Combination with Fluorescent Concentrator for Vehicular Visible Light Communication System

Abstract

Vehicle-to-vehicle communication based on visible light communication has gained much attention. This work proposes a smart license plate receiver incorporated with a fluorescent concentrator, enabling a fast vehicle-to-vehicle communication with a large field of view and high optical gain. Communication performance is experimentally analyzed using off-the-shelf light-emitting diode-based headlamps for low-latency direct line of sight channel. Additionally, a blue laser diode-based beam-steering and tracking system, through image processing of taillights with a steerable mirror, is investigated. Data rates of 54 Mbps from the headlamps and 532 Mbps from the beam-steering channel with ±25° are demonstrated. In addition, real-time video streaming through the beam-steering channel is presented.

“…Visible light communication (VLC) [ 1 ], as a new optical wireless communication method, has been explored for a wide range of applications, for example, indoor illumination and communication [ 2 , 3 , 4 , 5 ], indoor positioning [ 6 , 7 , 8 , 9 , 10 ], vehicle-to-vehicle communication [ 11 , 12 ] and vehicle–road coordination [ 13 , 14 ]. It is the most potential supplement to 5G wireless communication [ 15 , 16 , 17 ].…”
