The indirect free spatial optical communication system and the transmission method due to the wide band of the high-speed data

摘要

Mode of transportation (the airplane) in, the indirect free spatial optical communication system which transmits the high-speed data with wide band has, the transmitter which possesses the irregularity possible illuminant (11,12) with, the photodetector (43) the transmitter (11,12) from receives the light which is emitted, the receiver which is converted to the electric information (5a, 5b, 7a and 7b) with possesses. The transmitter (11,12) with the receiver, in order one common plane surface (8a and 8b) to face at least, it is provided, the transmitter (11,12) from the light which is emitted, before this light arrives in the aforementioned receiver, it reflects the aforementioned common plane surface. This time the free spatial communication system is formed, possesses, possessing the cell, the plural cells (Z1 and Z2), aforementioned cell respectively has with one which at least corresponds with one transmitter, receiver at least, the aforementioned cell (Z1 and Z2) as for formation, the crosstalk for the cell where it adjoins respectively is prevented, becomes independent respectively.
