Demonstration of Resonant Adaptive Mirrors

We present a novel continuous deformable mirror (DM). The mirror can be integrated into optical systems to compensate for multiple wavefront aberrations during real-time scanning of the human retina and other targets. Specifically, it can correct all seven of the wavefront aberrations dominant in ophthalmic applications. The mirror assumes the desired shape to correct an aberration via resonant electrostatic actuation. It eliminates the need for a large number of electrodes and dependence algorithm required for spatial control of segmented DMs. It also realizes an additional benefit of dynamic amplification, thereby increasing the stroke distance. In addition, we demonstrate that the fundamental (defocus) mode of the DM can be used to change the location of the focal point for a reflected laser beam by up to
$485\ \mu\mathrm{m}$
