OPTICAL TRANSMITTER AND ITS ADJUSTMENT METHOD

PROBLEM TO BE SOLVED: To automatically adjust, from remoteness, optical axes of an optical transmission line for which mirrors are combined. SOLUTION: The optical transmitter 10 comprises: an optical transmission 12 that composes the optical transmission line 11 by combining mirrors; a mirror adjustment devices 30, 31 that control the inclined angle of at least one mirror constituting this optical transmitting means; an electronic optical imaging means 55 installed on the extension of the optical axis on a light source side to be propagated on the optical transmission line 11; image processing targets 33-36 that are arranged near the mirror; an image processor 55 that arithmetically processes image information from the electronic optical imaging means 55 and that measures angular deviation of the mirror from a normal position based on the positional information of the image processing targets 33-36 contained in this image information; and a controller 29 that, with the angular deviation of the mirror input, makes the mirror adjustment devices driven.
