Method and apparatus for two-axis, high-speed beam steering
First Claim
1. A two-axis, beam-steering device, comprising:
- a support platform having a top surface;
a reflective surface situated on the top surface of the support platform;
a first galvanometer having a first rotational shaft which defines a first fixed rotational axis;
a second galvanometer having a second rotational shaft which defines a second fixed rotational axis oriented substantially orthogonally to the first rotational axis;
a first linkage extending along the first rotational axis and coupling the first galvanometer to the support platform; and
a second linkage extending along the second rotational axis and coupling the second galvanometer to the support platform, the first galvanometer being situated relative to the support platform so as to rotate the support platform about the first rotational axis, and the second galvanometer being situated relative to the support platform so as to rotate the support platform about the second rotational axis, thereby providing simultaneous rotation of the support platform about the first and second rotational axes as the reflective surface reflects a beam of electromagnetic energy incident to the reflective surface.

Abstract
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.
