Active Mirror for Power Beaming
First Claim
Patent Images
1. An actuated mirror assembly for redirecting an optical power beam through free space, the mirror assembly comprising:
- a reflective surface for reflecting a first portion of an optical power beam;
a mechanism for adjusting the reflective surface to redirect the reflected first portion of the optical power beam in at least one dimension; and
a power conversion device for receiving a second portion of the optical power beam to power the mechanism for adjusting the reflective surface.

Abstract
A mirror assembly with a reflecting surface is used to redirect a power beam through free space. The mirror assembly is actuated on at least one axis, and preferably at least two axes, so that it can move through many angles based on control signals from the power beaming system. The mirror assembly receives an optical transfer of power through free space from a power beam transmitter. Thus, the movement of the mirror is powered from the power beam itself. Two or more of these mirrors can be used in a power beaming system, thus creating many different beam paths through a volume of free space.
