Abstract
Examples of information beamforming technology for visible light communication (VLC) systems are provided. A VLC system can include an array of light emitting diode (LED) elements that can emit omni-directional light and control circuitry that can control individual LED elements of the array to sinusoidally vary the intensity of the omni-directional light emitted from the individual LED elements. A data carrying light beam can be generated within an information beam region by constructively combining sinusoidal intensity variations of the emitted omni-directional light and uniform intensity light can be generated outside the information beam region by destructively combining the sinusoidal intensity variations. The VLC system can include an optical detector that can detect sinusoidal intensity variations of a data carrying light beam and generate an output signal corresponding to the sinusoidal intensity variations. The output signal can be converted into digital symbols corresponding to the detected sinusoidal intensity variations.
