Imaging Lens And Illumination System

View page
US Patent:
7048379, May 23, 2006
Filed:
Mar 17, 2004
Appl. No.:
10/801573
Inventors:
Joseph Marion Miller - Tucson AZ, US
James Theodore Schwiegerling - Oro Valley AZ, US
Assignee:
The Arizona Board of Regents on behalf of the University of Arizona - Tucson AZ
International Classification:
A61B 3/10
A61B 3/00
A61B 3/14
US Classification:
351213, 351205, 351207, 351221, 351246, 600473, 600476
Abstract:
An imaging system and method for imaging an object, where an objective lens directs light to the object, a coupling lens receives light reflected from a surface of the object and transmitted through the objective lens, and focuses the reflected light as an image of the object, and an annular light emitter arranged concentrically with an optical axis of the objective lens and the coupling lens emits to the objective lens the light directed to the object.

Compact Snapshot Polarimetry Camera

US Patent:
8368889, Feb 5, 2013
Filed:
Apr 11, 2008
Appl. No.:
12/595079
Inventors:
James T. Schwiegerling - Tucson AZ, US
Eustace Dereniak - Tucson AZ, US
Michael W. Kudenov - Tucson AZ, US
Haitao Luo - New York NY, US
Kazuhiko Oka - Hokkaido, JP
Edward A. DeHoog - Long Beach CA, US
Assignee:
The Arizona Board of Regents on Behalf of the University of Arizona - Tucson AZ
International Classification:
G01J 4/00
US Classification:
356367
Abstract:
An imaging polarimeter optics unit comprising: a first polarization-sensitive beam-splitter optic, a retarder, a second polarization-sensitive beam-splitter optic, and an analyzer, through which input light passes in sequence, wherein the retarder and polarization-sensitive beam-splitters cause the input light to have optical components that provide different information about the state of polarization of the input beam is provided.

Diffractive Trifocal Lens

View page
US Patent:
20110292335, Dec 1, 2011
Filed:
Feb 12, 2010
Appl. No.:
13/201440
Inventors:
James T. Schwiegerling - Tucson AZ, US
Assignee:
The Arizona Board of Regents on Behalf of the University of Arizona - Tucson AZ
International Classification:
G02C 7/04
A61F 2/16
A61F 2/14
G02B 5/18
US Classification:
351161, 359571, 623 611, 623 511
Abstract:
A diffractive multifocal lens is disclosed, comprising an optical element having at least one diffractive surface, the surface profile comprising a plurality of annular concentric zones. The optical thickness of the surface profile changes monotonically with radius within each zone, while a distinct step in optical thickness at the junction between adjacent zones defines a step height. The step heights for respective zones may differ from one zone to another periodically so as to tailor diffraction order efficiencies of the optical element. In one example of a trifocal lens, step heights alternate between two values, the even-numbered step heights being lower than the odd-numbered step heights. By plotting a topographical representation of the diffraction efficiencies resulting from such a surface profile, step heights may be optimized to direct a desired level of light power into the diffraction orders corresponding to near, intermediate, and distance vision, thereby optimizing the performance of the multifocal lens.

Accommodating Intraocular Lens With Deformable Material

View page
US Patent:
20130110235, May 2, 2013
Filed:
Jun 29, 2011
Appl. No.:
13/806993
Inventors:
James T. Schwiegerling - Tucson AZ, US
Assignee:
The Arizona Board of Regents on Behalf of the University of Arizona - Tucson AZ
International Classification:
A61F 2/16
US Classification:
623 656
Abstract:
An accommodating intraocular lens. The lens includes a substantially-rigid anterior member having an extrusion aperture. First transparent deformable material is disposed anterior to the posterior side of the anterior member. Second transparent deformable material is disposed adjacent the posterior surface of the first material, the second material having a different degree of deformability than the first material and having an index of refraction different from the index of refraction of the first material. This forms a refractive deformable interface between the body of first material and the body of the second material. Force applied to the second material causes that material to be extruded through the aperture so as to form a curved, refractive interface with the body of first material. A method for installation of the accommodating intraocular lens is also provided.

Variable Focal Length Achromatic Lens System

View page
US Patent:
20130286309, Oct 31, 2013
Filed:
Apr 4, 2013
Appl. No.:
13/857032
Inventors:
The Arizona Board of Regents on Behalf of the University of Arizona - , US
Nickolaos Savidis - Tucson AZ, US
James T. Schwiegerling - Tucson AZ, US
Gholam Peyman - Sun City AZ, US
Nasser N. Peyghambarian - Tucson AZ, US
International Classification:
G02B 5/18
G02F 1/137
US Classification:
349 35, 359565, 264 136
Abstract:
A variable focal length achromatic lens includes a flat liquid crystal diffractive lens and a pressure-controlled fluidic refractive lens. The diffractive lens is composed of a flat binary Fresnel zone structure and a thin liquid crystal layer, producing high efficiency and millisecond switching times while applying a low ac voltage input. The focusing power of the diffractive lens is adjusted by electrically modifying the sub-zones and re-establishing phase wrapping points. The refractive lens includes a fluid chamber with a flat glass surface and an opposing elastic polydimethylsiloxane (PDMS) membrane surface. Inserting fluid volume through a pump system into the clear aperture region alters the membrane curvature and adjusts the refractive lens' focal position. Primary chromatic aberration is remarkably reduced through the coupling of the fluidic and diffractive lenses at a number of selected focal lengths. Potential applications include miniature color imaging systems, medical and ophthalmic devices, or any design that utilizes variable focal length achromats.

Image Modifiers For Use In Scanning Photographic Images

View page
US Patent:
62020404, Mar 13, 2001
Filed:
May 20, 1999
Appl. No.:
9/314940
Inventors:
James T. Schwiegerling - Tucson AZ
William F. Coyer - Princeton NJ
Assignee:
The University of Arizona - Tucson AZ
International Classification:
G06F 9455
G03B 1100
US Classification:
703 6
Abstract:
A system and a method for modifying an original image to simulate a painting effect, wherein an irregularly translucent diffusion element is configured to be overlayed with an original image such as a photograph or picture and a scanner or photocopier is configured to scan an imaging area adjacent the original image overlayed with the diffusion element and produce image data representative of the original image modified by the diffusion element. Alternatively, the painting effect can be simulated in software to produce shifts in pixels of original image data and display a distorted image with painting effect based on the shifts in pixel values.
