ABSTRACT:
Each optical transceiver comprises a photoemissive device for generating a signal light of near-infrared rays, a photoreceptor for receiving the signal light of the near-infrared rays, and an optical lens for converting the signal light outputted from the photoemissive device into a substantially collimated light so as to emit the light into a desired direction and for guiding the signal light from the same direction to the photoreceptor. Directivities of the respective optical transceivers are directed to the same portion on the indoor optical diffusing surface such as a ceiling.
