Abstract
The technology relates to the design and placement of beacon transmission optics for free space optical communications ('FSOC'). One aspect of the disclosure provides an FSOC device with a beam steering mechanism, a beam column with a beam expander, an optical bus, and beacon transmission optics. The beacon transmission optics includes a prism that directs outgoing beacon beams into the beam column, and toward the beam steering mechanism. In one embodiment, the outgoing beacon beams do not need to travel through the beam expander of the beam column. As a result, backscatter is minimized and incoming or outgoing beams can be controlled with a single beam-steering mechanism.
