Abstract:
1. An apparatus comprising: a deformable mirror, wherein the deformable mirror comprises a reflective surface and a plurality of dispersion-force-based actuators that deform the reflective surface responsive to a drive signal; a wavefront sensor, wherein the wavefront sensor obtains measurements that are indicative of aberrations in the wavefront of a first light beam reflected from the deformable mirror; and a drive signal generator, wherein the drive signal generator generates the drive signal, wherein the drive signal comprises a plurality of light beams for actuating the plurality of dispersion-force-based actuators, wherein a characteristic of each of the light beams is individually controlled as a function of the measurements obtained by the wavefront sensor, and wherein a value of the characteristic of each light beam affects an amount of movement of respective actuators.
