Patent number: 11366253Abstract: Methods, systems and devices for diffractive waveplate lens and mirror systems allowing electronically pointing and focusing light at different focal planes. The system can be incorporated into a variety of optical schemes for providing electrical control of transmission. In another embodiment, the system comprises diffractive waveplates of different functionality to provide a system for controlling not only focusing but other propagation properties of light including direction, phase profile, and intensity distribution. The diffractive waveplate lens and mirror systems are applicable to optical communication systems.Type: GrantFiled: January 17, 2020Date of Patent: June 21, 2022Assignees: Beam Engineering for Advanced Measurements Co., U.S. Government as Represented by the Secretary of the ArmyInventors: Nelson V.

Patent number: 11119257Abstract: Methods of fabricating optical lenses and mirrors, systems and composite structures based on diffractive waveplates, and fields of application of said lenses and mirrors that include imaging systems, astronomy, displays, polarizers, optical communication and other areas of laser and photonics technology. Diffractive lenses and mirrors of shorter focal length and larger size, with more closely spaced grating lines, and with more exacting tolerances on the optical characteristics, can be fabricated than could be fabricated by previous methods.Type: GrantFiled: December 7, 2018Date of Patent: September 14, 2021Assignees: Beam Engineering for Advanced Measurements Co, U.S. Government as Represented by the Secretary of the ArmyInventors: Nelson V. Tabirian, Svetlana Serak, David E. Roberts, Diane Steeves, Brian Kimball

Patent number: 10802302Abstract: The invention provides for lenses fabricated as planar thin film coatings with continuous structure. The lensing action is due to optical axis orientation modulation in the plane of the lens. The lenses of the current invention are fabricated using photoalignment of a liquid crystal polymer wherein the polarization pattern of radiation used for photoalignment is obtained by propagating the light through an optical system comprising a shape-variant nonlinear spatial light polarization modulators.Type: GrantFiled: October 24, 2018Date of Patent: October 13, 2020Assignees: Beam Engineering for Advanced Measurements Co., The United States of America as Represented by the Secretary of the ArmyInventors: Nelson Tabirian, Svetlana Serak, Diane Steeves, Brian Kimball
