Abstract:
1. A free space optics link including a first and a second free space optics apparatuses wherein said first free space apparatus comprising: a light source including at least an emitting portion, emitting a first light beam into free space, attached to a first actuated mechanical assembly with at least two degrees of freedom; a first photodetector including at least a receiving portion attached to a second actuated mechanical assembly, with at least two degrees of freedom, that can adjust the position of the photodetector receiving portion independently of the position of the light source emitting portion; a controller that can step said first actuated mechanical assembly through a range of positions and can adjust the position of the light source emitting portion to a position indicated by incoming alignment information received from the second free space optics apparatus, by controlling said first actuated mechanical assembly, and can step said second actuated mechanical assembly through a range of positions, independently of the movement of the first actuated mechanical assembly, and can adjust the position of the photodetector receiving portion, independently of the position of the light source emitting portion, to a position indicated by response values generated by said first photodetector due to incoming alignment signals received from the second free space optics apparatus, by controlling said second actuated mechanical assembly.
