WIRELESS VISIBLE LIGHT OPTICAL COMMUNICATION SYSTEM

摘要

A wireless visible light communication system is provided to maintain its display in uniform natural light state by additionally generating at least light having another wavelength which has the same color as the color of an optical signal in which data are modulated. A wireless visible light communication system(200) which includes optical receivers and transmitters comprises: a first light source(213a) for generating an optical signal; a second light source(213b) which generates light having wavelength of which color is same as the color of the optical signal; and a controller(230) which is connected to a path, at which data(data1-data3) are inputted to each optical transmitter(211-213), by a tap filter, compares each data strengths by dividing some portion of each data, and controls the strengths of second light sources(211b-213b) in each optical transmitter.
