1. An apparatus comprising:
an optical reflector comprising a solid transmissive material and a reflective surface, wherein the transmissive material is positioned to refract incident light toward the reflective surface, and wherein the solid transmissive material has a first surface; and
a motor configured to rotate the optical reflector about an axis of rotation, wherein a normal to the reflective surface is not parallel to the axis of rotation, wherein light which enters the transmissive material through the first surface and reflects off the reflective surface also exists exits the transmissive material through the first surface as a scanned beam.
