Optical camera communications link using an LED-coupled illuminating optical fiber [PDF]

Optics Letters, 2021
In this Letter, we propose and demonstrate a novel wireless communications link using an illuminating optical fiber as a transmitter (Tx) in optical camera communications. We demonstrate an indoor proof-of-concept system using an illuminating plastic optical fiber coupled with a light-emitting diode and a commercial camera as the Tx and the receiver ...

400  m rolling-shutter-based optical camera communications link [PDF]

Optics Letters, 2020
In this Letter, we develop a novel technique, to the best of our knowledge, to increase the link span ( L s ) of a rolling shutter (RS)-based optical camera communications (OCC) system by reducing the spatial bandwidth of the camera in the out-of-focus regions.

A Security Protocol for Vehicle Platoon Verification Using Optical Camera Communications

IEEE Transactions on Intelligent Transportation Systems
In autonomous vehicle platooning, members of the platoon not only use their own sensor data for making driving decisions. They also rely on data shared by other members of the platoon.
