MOBILE OPTICAL COMMUNICATION SYSTEM AND MOBILE OPTICAL COMMUNICATION METHOD

摘要

A mobile optical communication system (1) includes a railway (2) and a train (3). A plurality of leaky optical fibers (10), a plurality of optical fibers (20), and a plurality of light receivers (21) are located along the railway. The leaky optical fiber includes light leaking parts (13). The light leaking parts are disposed discontinuously along the longitudinal direction and arranged at intervals less than or equal to a length of the train with respect to a traveling direction of the train. A plurality of light receivers (32), that are disposed on the train, are arranged along the entire length of the train in the direction of travel at intervals less than or equal to a fixed length. Two neighboring light transmitters, that are disposed on the train, are arranged so that optical images of light from the two neighboring light transmitters toward the optical fiber have an overlapping region with respect to the traveling direction.
