Abstract:
A process for simultaneously providing illumination that is free to the eye of flicker and other distracting optical phenomena and for providing communication comprising the steps of:providing a source of data comprising elements selected from a group consisting of analog data, digital data, control codes and start codes; providing a design of an illumination means in which the illumination means can be modulated; analyzing the nature of the data from the source of data and the design of the illumination means, to determine if the nature of the data and the design of the illumination means can create flicker visible to the eye or other distracting optical phenomena in the output of the illumination means; based on the analysis, selecting an encoding means for the data such that it can be transmitted by modulating the illumination means without creating flicker or other distracting optical phenomena which are visible to the eye; providing an illumination means based on said design of an illumination means; providing a medium means through which the illumination passes; providing a receiver means for receiving and processing the modulated illumination from the illumination means and extracting the encoded data; providing a user means for using the data processed by the receiver means; transmitting data from the source of data to the illumination means which then transmits the encoded data by modulating the illumination means without creating flicker or other distracting optical phenomena which are visible to the eye to the receiver means which receives and processes the modulated illumination, extracts the encoded data and supplies it to the user means.
