Abstract
A system and method for dispersion-force-based actuation are disclosed. In some embodiments, a light beam is used to change the dispersion force between two spaced apart surfaces. The change in the dispersion force causes a change in the gap between the surfaces. The actuation system can be used in conjunction with a deformable mirror to provide an improved adaptive optics system.

(canceled)
A method comprising:
- reflecting a first light beam off of a reflective surface of a deformable mirror;
- generating a control signal based on the reflected first light beam;
- generating an optical drive signal based on the control signal;
- and
- propagating the optical drive signal to a portion of a dispersion-force-based-actuation system that deforms the reflective surface responsive to the optical drive signal.
2 more elements
A method comprising:
- reflecting a first light beam off of a reflective surface of a deformable mirror;
- measuring aberrations in a wavefront of the first light beam;
- generating a drive signal based on the measured aberrations;
- and
- deforming the reflective surface of the deformable mirror by receiving the drive signal at a plurality of actuators that deform the reflective surface of the deformable mirror when actuated by the drive signal, wherein a force that causes the actuators to move in response to the drive signal is a dispersion force.

A method comprising:
- reflecting a first light beam off of a reflective surface of a deformable mirror;
- distributing the energy of a portion of the reflected first light beam into a plurality of spatially-separated light beams;
- and
- deforming the reflective surface of the deformable mirror by receiving the plurality of spatially-separated light beams at a plurality of dispersion-force-based actuators.
