Method For Using A Deep Image Hologram As A Security Device And A Deep Image Hologram

View page
US Patent:
7576898, Aug 18, 2009
Filed:
Aug 27, 2004
Appl. No.:
10/928892
Inventors:
William J. Molteni - Wilmington DE, US
Michael G. Fickes - Kennett Square PA, US
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
G03H 1/00
US Classification:
359 2, 430 10, 283 86
Abstract:
A holographic optical element (HOE) that includes a deep image hologram and a method for using this HOE as a security device are described. The deep image hologram is viewable with a collimated or at least partially collimated light source having a center wavelength in the visible region of the electromagnetic spectrum and a spectral bandwidth, wherein the spectral bandwidth of the collimated or at least partially collimated light source at least partially overlaps the spectral bandwidth of the deep image hologram. The deep image hologram is not viewable (i. e. , appears essentially unrecognizable to the human eye) with a diffuse lighting source, such as ordinary room lighting.

Information-Recorded Medium Containing A Holographically-Recorded Bar Code And Associated Methods

View page
US Patent:
20070040032, Feb 22, 2007
Filed:
Jul 26, 2006
Appl. No.:
11/493051
Inventors:
William Molteni - Nibley UT, US
International Classification:
G06K 7/10
G06K 19/00
US Classification:
235462010, 235487000
Abstract:
An information-recorded medium that contains a holographically-recorded bar code and a method for using this medium to achieve enhanced security and authentication of bar code readings in commerce are described. The holographically-recorded bar code is virtually impossible to copy by non-holographic means and is readable using conventional bar code scanners that are currently in use. The holographically-recorded bar code can be made either visible or invisible to the human eye and can be made responsive to electromagnetic radiation in the visible, ultraviolet, and infrared regions of the spectrum.

Security Hologram And Associated Methods Of Use And Of Making

View page
US Patent:
20070103746, May 10, 2007
Filed:
Nov 6, 2006
Appl. No.:
11/593339
Inventors:
William Molteni - Nibley UT, US
International Classification:
G03H 1/02
US Classification:
359007000
Abstract:
A security hologram is described that contains an integral image, which is made up of at least a first holographic image, which is located at or near a surface of a recording medium used to record the hologram, and a second holographic image, which is located in either a foreground position or a background position relative to the surface of the recording medium. The at least first and second holographic images fit together like pieces of a jigsaw puzzle to afford the integral image. The second holographic image is viewable and recognizable only with a collimated or at least partially collimated light source having a center wavelength in the visible region of the electromagnetic spectrum and a spectral bandwidth, wherein the spectral bandwidth of the collimated or at least partially collimated light source overlaps the spectral bandwidth of the hologram. Also described are associated methods of use of the hologram in security/authentication applications and a method of making the hologram.

Display System With Spatial Light Modulator Illumination For Divided Pupils

View page
US Patent:
20180284460, Oct 4, 2018
Filed:
Mar 21, 2018
Appl. No.:
15/928015
Inventors:
- Plantation FL, US
Chulwoo Oh - Cedar Park TX, US
Clinton Carlisle - Parkland FL, US
Michael Anthony Klug - Austin TX, US
William Molteni - Plantation FL, US
International Classification:
G02B 27/09
G02B 27/10
G02B 27/01
Abstract:
Illuminations systems that separate different colors into laterally displaced beams may be used to direct different color image content into an eyepiece for displaying images in the eye. Such an eyepiece may be used, for example, for an augmented reality head mounted display. Illumination systems may be provided that utilize one or more waveguides to direct light from a light source towards a spatial light modulator. Light from the spatial light modulator may be directed towards an eyepiece. Some aspects of the invention provide for light of different colors to be outcoupled at different angles from the one or more waveguides and directed along different beam paths.
