Claim 11:
12. The optical transceiver of claim 11, wherein the location sensor includes a first location sensor and a second location sensor installed in a frame of the optical transceiver,
the location indicator includes a first location indicator and a second location indicator installed in the reflector,
the first location sensor transceives light with the first location indicator, and detects whether the reflector is located at a predetermined first location in a state where the second gear is rotated in a first direction,
the second location sensor transceives light with the second location indicator, and detects whether the reflector is located at a predetermined second location in a state where the second gear is rotated in a second direction, and
when the optical transceiver is changed from a scan mode to a correction mode,
the optical transceiver measures a first location of the reflector based on the first location indicator by rotating the reflector in the first direction and the controller stores a first reference location of the first driving unit corresponding to the first location,
the optical transceiver measures a second location of the reflector based on the second location indicator by rotating the reflector in the second direction and the controller stores a second reference location of the first driving unit corresponding to the second location, and
the controller corrects the first reference location and the second reference location.
