Methods and Apparatus for Two-Axis, High-Speed Beam Steering

摘要

Dual axis, beam-steering devices are disclosed. An exemplary device includes a support platform having a top surface. A reflective surface is coupled to the top surface of the support platform. First and second galvanometers are coupled via respective linkages to the support platform such that the first galvanometer rotates the support platform about a first rotational axis, and the second galvanometer rotates the support platform about a second rotational axis that is orthogonal to the first rotational axis. The support platform can be simultaneously rotated with respect to both the first rotational axis and the second rotational axis to steer a beam of electromagnetic energy (e.g. light beam) reflected by the reflective surface.
