OPTICAL ANTENNA SYSTEM FOR OPTICAL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To simplify handling including adjustment work in addition to expediting miniaturization. SOLUTION: A guide optical system 11 is arranged at the point part of an optical antenna 10 through an azimuth angle adjustment mechanism 13 and an elevation angle adjustment-mechanism 15 so as to be able to freely adjust its angle around an optical axis and around two axes crossing almost orthogonally with the optical axis, and the opposite communication station (unillustrated) is tracked to perform an optical communication by performing angle adjustment of the optical system 11 around two axes.
