  • Method and system for data transmission and communication using imperceptible differences in visible light
    Patent number: 9917644
    Abstract: An exemplary system for communicating data includes a light source that emits light and a processing device that receives and encodes data into a communication signal. A modulator modulates light emitted by the light source, wherein the modulation is imperceptible to the human eye, and the modulated light includes the encoded data. The modulation of the transmitted light is imperceptible to a human eye. A receiving device receives the modulated light and processes the light to decode the encoded signal and obtain the data.
