1. A system comprising:
a base;
a mirror assembly rotationally coupled to the base and comprising a mirror, the mirror assembly configured to rotate around only a single rotation axis;
a reaction inertia assembly rotationally coupled to the base, the reaction inertia assembly configured to rotate around only the single rotation axis; and
an actuator configured to drive rotation of the mirror assembly and the reaction inertia assembly;
wherein a first end of the mirror is rotationally coupled to the base and a second end of the mirror is not supported by or attached to another structure; and
wherein the mirror assembly includes first and second flexures disposed on opposite sides of a center of gravity of the mirror assembly and configured to support the mirror assembly, the first and second flexures disposed along the single rotation axis.
