Title: Method and apparatus for communication in an illumination system using a liquid lens

Abstract: A method and apparatus for communicating information content by modulation of light in an illumination system via a liquid lens optically coupled to the illumination system and capable of modulation of light thereof, using resonant modes of the liquid lens. A modulation control system operatively coupled to the liquid lens and to the information content is configured to represent at least a portion of the information content as a time-varying configuration of the liquid lens, the time-varying configuration substantially including one or more of said one or more resonance modes. A receiver system optically coupled to the liquid lens is configured to reconstruct at least a portion of the information content from light modulated by the time-varying configuration of the liquid lens.
