UNDERWATER OPTICAL WIRELESS COMMUNICATION SYSTEM, UNDERWATER OPTICAL WIRELESS COMMUNICATION METHOD, AND UNDERWATER MOVING BODY

This underwater optical wireless communication system (100) is provided with a plurality of moving bodies (1) capable of moving in water. The plurality of moving bodies each includes an optical wireless communication unit (3) configured to perform bidirectional communication between the plurality of moving bodies using communication light beams (30) having wavelengths different from each other in a plurality of directions which are mutually opposite directions. The optical wireless communication unit is configured to perform bidirectional communication between the plurality of moving bodies using communication light beams, the communication beams having the same wavelength with respect to each of the plurality of directions between the plurality of moving bodies.
