Abstract: An optical beam is provided from a transmitter aperture to a receiver aperture that receives the optical beam after displacement by a path shifting component. Received initial displacement information characterizing at least one of: an initial estimate of the displacement, or an indication that the displacement is below a predetermined threshold. Received input beams each have a different spatial mode, from a set of mutually orthogonal spatial modes that include: a lowest order spatial mode, a highest order spatial mode, and one or more intermediate order spatial modes. A relative amount of each of the input beams to be included in the optical beam is determined based at least in part on: corresponding diffraction loss estimates for each of the input beams, and the initial displacement information. One of the input beams that has a largest relative amount in the optical beam is one of the intermediate order spatial modes.
