Journal ArticleDOI
Diffractive Alvarez lens
Ian M. Barton,Sham N. Dixit,Leslie J. Summers,Charles A. Thompson,Kenneth Avicola,Julia Wilhelmsen +5 more
TL;DR: A diffractive Alvarez lens is demonstrated that consists of two separate phase plates, each having complementary 16-level surface-relief profiles that contain cubic phase delays that produce a variable astigmatic focus.

Adaptive ophthalmologic system
Scot S. Olivier,Charles A. Thompson,Brian J. Bauman,Steve M. Jones,Don T. Gavel,Abdul A. S. Awwal,Stephen K. Eisenbies,Steven J. Haney +7 more
TL;DR: In this paper, a system for improving vision that can diagnose monochromatic aberrations within a subject's eyes, apply the wavefront correction, and then enable the patient to view the results of the correction is presented.
Proceedings ArticleDOI
Free Space Optical Communications Utilizing MEMS Adaptive Optics Correction
Charles A. Thompson,Michael W. Kartz,Laurence M. Flath,Scott Wilks,Richard A. Young,Gary W. Johnson,Anthony J. Ruggiero +6 more
TL;DR: In this paper, the authors proposed a method to improve signal quality through the use of adaptive optics for horizontal and slant path laser communications, which relies heavily on recent progress in MicroElectro-Mechanical Systems (MEMS) deformable mirrors, as well as improved communication and computational components.
Proceedings ArticleDOI
Modeling of adaptive-optics-based free-space communications systems
Scott Wilks,J. R. Morris,James M. Brase,Scot S. Olivier,John R. Henderson,Charles A. Thompson,Michael W. Kartz,A. J. Ruggerio +7 more
TL;DR: In this article, a wave-optics based simulation code written to model a complete free space laser communications link, including a detailed model of an adaptive optics compensation system, is presented, where the phase of a communications laser beam is corrected, after it propagates through a turbulent atmosphere.
Journal ArticleDOI
Design of near-field irregular diffractive optical elements by use of a multiresolution direct binary search method.
TL;DR: A multiresolution direct binary search iterative procedure is used to design small dielectric irregular diffractive optical elements that have subwavelength features and achieve near-field focusing below the diffraction limit.
