1. A method of multiplexed free-space optical communications (FOC), comprising:
providing modulated light associated with one or more communication channels with a light source;
providing the modulated light associated with the one or more communication channels to a plane with a pixel controller, wherein the pixel controller directs the modulated light associated with each of the one or more communication channels to a different location of the plane, wherein the plane corresponds to a focal plane of an imaging lens assembly; and
collimating, with the imaging lens assembly, the modulated light associated with any of the one or more communication channels from the plane as one or more separate free-space optical communications (FOC) beams, wherein each of the one or more separate FOC beams associated with the one or more communication channels is a collimated beam that emanates from the imaging lens assembly at a different line-of-sight (LOS) angle based on an associated location in the plane.
