MOBILE OPTICAL COMMUNICATION SYSTEM AND MOBILE OPTICAL COMMUNICATING METHOD

WIPO Patent Application WO/2007/123084

A1

[PROBLEMS TO BE SOLVED] A mobile optical communication system and a mobile optical communicating method are provided to carry out high speed and high quality mobile communication. [MEANS FOR SOLVING THE PROBLEMS] A transmitting unit (21) includes a light source (22) for modulating a light signal in accordance with transmitting information, and an optical member (23) for expanding the modulated light in one-dimensional direction along a moving direction of a mobile member (11). The mobile member (11) is provided with a light receiving unit (12) for receiving the light signal from the transmitting unit (21), and a demodulating unit (13) for demodulating the received signal, so that information can be received. As the mobile member (11) moves, the light receiving unit (12) moves along a pattern of the light signal expanded in the one-dimensional direction and can receive the light and the information only until the mobile member (11) moves in the width of the pattern. If the transmitting unit (21) is provided at every prescribed distance, it is possible to carry out continuous communication.
