<P>PROBLEM TO BE SOLVED: To provide a free space optical bus system and a method for connecting two circuit units of across a free space gap. <P>SOLUTION: A first circuit unit includes a multiplexer that combines a plurality of bus signals to obtain an electronic combined signal and a laser that is driven by the electronic combined signal to transmit an optical signal. A second circuit unit is separated from the first circuit unit by a free space gap. The second circuit unit includes a photodetector that receives the optical signal and transforms it into an electronic composite signal and a demultiplexer that divides the electronic composite signal into a plurality of constituent signals. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
