Claim 5:
6. 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 spectroscopes configured to split an optical signal through the light receiving
movable lens to transmitted light and reflected light;
an optical power detector configured to measure optical reception intensity of communication light incident on the reception optical fiber cable; and
a controller configured to measure light reception intensity by the optical power detector at a current control position of the movable light receiving lens and at one or more measurement positions of the movable light receiving lens apart from a predetermined distance from the current control position, and further configured to move the movable light receiving lens to the measurement position where the measured light reception intensity is the highest.
