Claim 2:
3. The spatial optical transmission apparatus according to claim 1, comprising:
a first movable light receiving lens on an optical signal path of an optical signal from the third port that enters the reception optical fiber cable;
a first spectroscope on the optical signal path, configured to provide first light based on the optical signal;
a second movable light receiving lens on the optical signal path;
a second spectroscope on the optical signal path, configured to provide second light based on the optical signal;
a first position sensor configured to receive the first light and further configured to detect a first position of an optical axis of the optical signal; and
a second position sensor configured to receive the second light and further configured to detect a second position of the optical axis of the optical signal,
wherein the first spectroscope is disposed between the first and second movable light receiving lenses and the second movable light receiving lens is between the first and second spectroscopes, and
wherein the controller is configured to perform first Proportional-Integral-Differential (PID) control on the first movable light receiving lens based on the first position of the optical axis detected by the first position sensor, and further configured to perform second PID control on the second movable light receiving lens based on the second position of the optical axis detected by the second position sensor.
