1. a free space 90 °

  • of optical mixer units, comprise the conjunction Shu Danyuan carrying out closing bundle to signal beams and local beam, produce the homophase balance reception passage of 0 ° and

    180 °

    relative phase shift two-way beam combination, produce the orthogonal balanced receiving cable of 90 ° and

    270 °

    relative phase shift two-way beam combinations, receive the receiving element of 0 °

    , 90 °

    , 180 °

    , 270 °

    relative phase shift beam combination;

    It is characterized in that;

    Described homophase balance reception passage and orthogonal balanced receiving cable are respectively arranged with a lateral shearing interferometer;

    The half pentagonal prism gummed that described lateral shearing interferometer comprises two pieces of thickness different forms, ECDC Shu Danyuan close bundle after light beam be cut into two light beams through lateral shearing interferometer again, when debuging by two and half pentagonal prisms in cemented surface translation to control the spacing of two light beams emergent light.
