Abstract
(EN)
Disclosed are an optical communication device and a method for transmitting and receiving information. The optical communication device comprises: at least two light sources, including a first light source and a second light source; and a controller capable of driving the first light source and the second light source by means of at least two driving modes, the at least two driving modes including a first driving mode and a second driving mode and the first driving mode and the second driving mode having the same frequency or different frequencies. When the first light source and the second light source are driven in the same driving mode, the optical communication device is used for transmitting first information, and when the first light source and the second light source are driven in different modes, the optical communication device is used for transmitting other information different from the first information.

La présente invention concerne un dispositif de communication optique et procédé pour transmettre et recevoir des informations. Le dispositif de communication optique comprend : au moins deux sources lumineuses, y compris une première source lumineuse et une seconde source lumineuse ; et un dispositif de commande capable d'exciter la première source lumineuse et la seconde source lumineuse d'au moins deux modes d'excitation, les deux, ou plus, modes d'excitation comprenant un premier mode d'excitation et un second mode d'excitation et le premier mode d'excitation et le second mode d'excitation ont la même fréquence ou des fréquences différentes. Lorsque la première source lumineuse et la seconde source lumineuse sont excitées dans le même mode d'excitation, le dispositif de communication optique est utilisé pour transmettre des premières informations, et lorsque la première source lumineuse et la seconde source lumineuse sont excités dans des modes différents, le dispositif de communication optique est utilisé pour transmettre d'autres informations différentes des premières informations.
