Plasmonic metamaterials for optical wavefront control

Frontiers in Optics 2011/Laser Science XXVII, 2011
We discuss progress in the development of devices containing arrays of resonant apertures utilizing phase shifts accompanying resonance. We show that lenses producing three-dimensional focussing and planar quarter-wave plates can be created.

Experiments On Wavefront Control Using Wavefront Sensing And Hill Climbing Techniques

SPIE Proceedings, 1989
A number of experiments have been made with two adaptive optical systems. A 19 element deformable mirror with serial hilt-climbing control system is used to correct static wavefront errors. A system with 21-element deformable mirror and real-time wavefront sensing with shearing interferometer is used to correct dynamic errors.

Wavefront Reconstruction and Control Systems

1998
Abstract The control system is the vital link between the wave front sensor and the wavefront corrector in all adaptive optics systems. Its function is to convert the wavefront measurements made by the sensor into a set of commands that are applied to the wavefront corrector to satisfy a suitable performance criterion, such as minimizing

Phase-Diverse Wavefront Sensing and Control

Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008
Improved computational capabilities render phase-diverse wavefront sensing to be a viable choice for selected adaptive-optics applications. Phase diversity acquires informative data with simple optical hardware, works with low-contrast extended scenes, and accommodates wavefront discontinuities.
