Abstract
Methods and apparatuses, including computer program code are disclosed. The apparatus may include at least one processor and at least one memory including computer program code. The at least one processor, the at least one memory, and the computer program code may be configured to cause the apparatus to generate a divergent beam for an optical source that is coincident with a divergent beam for an optical detector. The apparatus may determine an adjustment to a mirror to cause an optical alignment of an incoming beam with the optical detector based on at least an optical intensity across the optical detector, wherein the alignment is with respect to at least another apparatus. The apparatus may adjust a position of the mirror according to the determined adjustment, and change the divergent beam to a collimated beam to enable optical communications with the other apparatus via the collimated beam.
