Abstract:
1. A beam direction module comprising: a collimator support member including collimator lenses connected to optical fibers respectively; a first mirror substrate including first mirrors, and first windows; a first driving substrate including driving mechanisms for driving said first mirrors, and second windows; a second mirror substrate disposed on a side of said first mirror substrate opposite to a side on which said collimator support member is disposed, said second mirror substrate including second mirrors, and third windows; and a second driving substrate including driving mechanisms for driving said second mirrors, and fourth windows, wherein: beams emitted from said collimator lenses are formed so that said beams pass through said second windows and said first windows and are reflected on said second mirrors, said beams reflected on said second mirrors are radiated to said first mirrors, and said beams reflected on said first mirrors pass through said third windows and said fourth windows and are radiated to the outside; said beam direction module further comprises fixing members provided to pierce a stack of said first mirror substrate, said first driving substrate, said second mirror substrate and said second driving substrate in a direction of lamination; and said fixing members are formed so as to be connected to said collimator support member.
