Abstract :
In this paper, optical wireless communication systems based on a controller area network (CAN) are proposed and demonstrated. The optical transceiver is composed of 25 LED´s array around plus 3 PDs in the center and two CAN transceivers. By means of that, the conventional two-wired CAN bus replaces to the free-space optical channels. To ensure the full-duplex channel isolation, LED driving and PD receiving circuit have their own CAN transceiver, respectively. On-off keying was applied without observable flicker in the target modulation ranges. The performance of data transfer in our prototype shows up to 0.6 m range at the transmission rate of 200kbps.
