Abstract: A scanning-type optical antenna is provided, which includes a housing, a fine-tune mirror, a light signal emitter, a light signal receiver, a scanning light receiver and a rotational mechanism. The housing includes a window. The scanning light receiver disposed on the housing receives an input sector scanning light from a target antenna to generate plural light speckles. The rotational mechanism mounts the housing and adjusts the deflection angle between the housing and the target antenna according to the light speckles. The fine-tune mirror is disposed outside the housing and corresponding to the window. The light signal emitter inside the housing transmits an output signal light to the target antenna after being reflected by the fine-tune mirror through the window. The input signal light of the target antenna is transmitted to the light signal receiver inside the housing after being reflected by the fine-tune mirror and passing through the window.
