Claim 0:
1. A spatial optical transmission apparatus comprising:
an optical circulator configured to receive a first optical signal from a transmission optical fiber cable at a first port, and to provide the first optical signal at a second port to a counterpart apparatus, and further configured to receive a second optical signal from the counterpart apparatus at the second port, and to provide the second optical signal at a third port;
at least one movable light projecting lens positionally adjustable in a plane substantially perpendicular to an optical axis of an optical signal through the second port outside the second port of the optical circulator;
at least one movable light receiving lens positionally adjustable in a plane substantially perpendicular to an optical axis of an optical signal through the third port outside the third port of the optical circulator;
at least one spectroscope configured to split an optical signal through the at least one movable light receiving lens into transmitted light and reflected light;
at least one position sensor configured to detect a position of an optical axis of either one of the transmitted light or reflected light from the spectroscope; and
a controller configured to adjust at least one of a position of the movable light receiving lens or the movable light projecting lens based on the position of the optical axis, and further configured to adjust the optical axis to cause the other of the transmitted light or reflected light from the spectroscope to enter a reception optical fiber cable.
