US Patent:

Filed:

May 2, 2001
Appl. No.:

09/681581
Inventors:

Richard A. Carreras - Albuquerque NM
Dan K. Marker - Albuquerque NM
James M. Wilkes - Sandia Park NM
Dennis Duneman - Albuquerque NM
James R. Rotge - Albuquerque NM
Assignee:

The United States of America as represented by the Secretary of the Air Force - Washington DC
International Classification:

G02B 510
US Classification:

359847, 359846, 359900, 264 19, 264 21, 264298, 264311
Abstract:

A method for fabricating an optical quality, free-standing, compliant parabolic membrane mirror using an inverted parabolic mandrel created by rotating a liquid confined to a cylindrical polymer and applying a reflective optical stress coating once the substrate has hardened. The stress coating applies a tensile force to the substrate that offsets the stress in the substrate that would otherwise decrease the convexity, and also generates a force to restore the membrane mirror to its original convex parabolic shape when the mirror is deformed by an external force.

Filed:

Mar 17, 2003
Appl. No.:

10/391319
Inventors:

Richard A. Carreras - Albuquerque NM

International Classification:

G02B 7188
US Classification:

359847, 359582, 359838, 359846
Abstract:

An optical quality, freestanding, compliant membrane mirror is cast with a concave parabolic shape, and includes a substrate and a reflective stress coating. The stress coating is in compression and applies a tensile shear stress to the substrate that opposes and offsets the intrinsic stress in the substrate that would otherwise decrease the concavity. The stress coating generates a force to restore the membrane mirror to its cast concave parabolic shape when an external force deforms the mirror.

US Patent:

7576308, Aug 18, 2009
Filed:

Jul 24, 2007
Appl. No.:

11/782547
Inventors:

Mark T. Gruneisen - Tijeras NM, US
Matthew B. Garvin - Wright Patterson Air Force Base OH, US
Raymond C. Dymale - Albuquerque NM, US
James R. Rotge - Albuquerque NM, US
Assignee:

The United States of America as represented by the Secretary of the Air Force - Washington DC
International Classification:

G01J 1/20
G01B 9/02
US Classification:

2502019, 356521
Abstract:

A wave front control system (“WFCS”) organizes the object scene into a mosaic comprised of a grid of segments and transmits each segment in a temporal sequence. The WFCS steers the light fronts emanating from each segment one segment at a time, through a series of optical components that transmit the light fronts respectively emanating from each segment onto a digital imaging sensor. An optical recording device records each sensed segment, and the object scene is composed by assembling the recorded segments. This abstract is provided to comply with the rules requiring an abstract, and is intended to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

US Patent:

56441223, Jul 1, 1997
Filed:

Jul 11, 1995
Appl. No.:

8/500615
Inventors:

Kenneth E. Siegenthaler - Colorado Springs CO
James R. Rotge - Albuquerque NM
Assignee:

Aptek, Inc. (Siegenthaler) - Colorado Springs CO
International Classification:

G02B 2304
US Classification:

250214VT
Abstract:

An optical system includes graded refractive index ("GRIN") optical elements. An objective optical element and an ocular optical element, each including at least one GRIN element, are located in an optical path which is substantially voidless. The optical system is not susceptible to fogging due to the absence of voids in the optical path. An image intensifier may be positioned in the optical path between the objective and ocular optical elements. The image intensifier responds primarily to invisible light and creates an amplified level of light substantially at a predetermined visible wavelength. A beam splitter may be used to split the light from the objective optical element into ranges of visible and invisible wavelengths. The range of visible light is directed through a first light channel to a beam combiner. The range of invisible light is directed through a second light channel to the image intensifier.

Filed:

Nov 2, 2000
Appl. No.:

9/704940
Inventors:

Richard A. Carreras - Albuquerque NM
Dan K. Marker - Albuquerque NM
James M. Wilkes - Sandia Park NM
Dennis Duneman - Albuquerque NM
James R. Rotge - Albuquerque NM
Assignee:

The United States of America as represented by the Secretary of the Air
Force - Washington DC
International Classification:

G02B 508
G02B 7182
US Classification:

359846
Abstract:

A membrane mirror having an optical quality spherical shape maintained by differential pressure takes a near parabolic shape when a plunger-induced displacement of the central area of the mirror is introduced. The focal length can be adjusted by varying the differential pressure.
