Abstract: A beam generating apparatus includes a laser light source, a speckle suppressing module, a light homogenizing module and a driving unit. The laser light source outputs a laser beam. The speckle suppressing module includes two biconic lenses and a diffuser. The first biconic lens is disposed on a transmission path of the laser beam. The diffuser is located on the transmission path of the laser beam between the first and second biconic lenses. The light homogenizing module is disposed on the transmission path of the laser beam from the second biconic lens. The driving unit drives the diffuser to move with respect to the laser beam so that the ratio of the M2 of the laser beam exiting from the second biconic lens in a first direction to the M2 thereof in a second direction is greater than 2, wherein the two directions are substantially perpendicular to each other.

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.
