Design of LED Array Control Module for Optical Camera Communication

Visible light communication technology is a communication system that uses light-emitting diodes as the emission source and electronic devices equipped with cameras or photodiodes as the receiving end. Optical camera communication, also known as optical imaging communication, belongs to a special kind of visible light communication, using image sensors as receivers. In this paper, an LED array control module for optical camera communication is designed, which realizes the data generation and signal transmission functions of the transmitter of the optical imaging communication system, and performs signal output and data transmission tests in indoor and outdoor environments.
