1. An imaging transmitter (Tx), comprising:
one or more light sources for providing modulated light associated with one or more communication channels;
a pixel controller configured for providing the modulated light associated with the one or more communication channels to a plane, wherein the pixel control directs the modulated light associated with each of the one or more communication channels to a different location of the plane; and
an imaging lens assembly, wherein the plane corresponds to a focal plane of the imaging lens assembly, wherein the imaging lens assembly is configured to collimate 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 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 the associated location in the plane.
