摘要：<p>PURPOSE: A communication link arranging method using a retroreflector in visible light communication and a device for the same are provided to perform bi-directional communication arrangement only with one directional visible light transmission when visible light communication using the retroreflector. CONSTITUTION: A visible light transmission unit(120) outputs a communication setup signal for communication direction setup and a data transmission signal in the form of visible light. The visible light reception unit(130) receives a visible light signal. A retroreflector(150) retroreflects the received visible light signal. A control unit(110) receives the communication setup signal from the retroreflector to retroreflect the signal. The control unit establishes a communication direction of the visible light transmission unit to a retroreflected direction.</p>
