Abstract
A optical communication system including a source device and an endpoint device. The source device include an array of laser diodes and is configured to drive the laser diodes to project a sequence of patterns into the field of view of the source device to define a set of serially-projected codes, each of which isolated to one respective angular division of the field of view of the source device. The endpoint device receives a serially-projected code from the source device which varies based which angular division of the field of view of the source device is occupied by the endpoint device.
