A scanning system of a wireless optical sensor network is provided to obtain high energy efficiency by using a pattern which reversely reflects a light source by using a sensor node including an orthogonal reverse reflector. A wireless optical sensor network system includes a light source(102), a scanning mirror, at least one sensor node(108,110), a beam splitter(104) and a synchronization unit(100). The scanning mirror is formed to be rotary at a constant angle on an advance path of an optical signal, and adjusts the advance path of the optical signal by reflecting the optical signal. At least one sensor node reflects an optical signal reflected from the scanning mirror, and the beam splitter passes or reflects the optical signal reflected from the sensor node. |
