Publication number: 20230367132Abstract: 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.Type: ApplicationFiled: May 23, 2023Publication date: November 16, 2023Inventors: Hui-Chuan Cheng, Chulwoo Oh, Clinton Carlisle, Michael Anthony Klug, William J. Molteni, Jr.

Patent number: 7576898Abstract: 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.Type: GrantFiled: August 27, 2004Date of Patent: August 18, 2009Assignee: E. I. du Pont de Nemours and CompanyInventors: William J. Molteni, Michael G. Fickes

Patent number: 5886799Abstract: The present invention provides a polarizing holographic reflector module useful in the manufacture of a holographically-illuminated liquid crystal display assembly by combination thereof with a partial LCD stack. The polarizing holographic reflector module is substantially quadrangular in shape and comprises a reflective holographic diffuser, a light polarizer, a pressure sensitive adhesive, and a removable protective liner. A method of manufacture is also provided wherein a web of polarizer material having a linear or downweb orientation is roll-to-roll laminated to a web of angularly offset reflective holographic diffusers.Type: GrantFiled: March 27, 1997Date of Patent: March 23, 1999Assignee: Polaroid CorporationInventors: William J. Molteni, Philip J. Ralli

Patent number: 5663815Abstract: Heads-Up and heads-down displays employing holographic stereograms are provided. The stereograms can be oriented perpendicular to the user's line of sight (the 90.degree. case) or at angle to the line of sight (the "non-90.degree. case"). The stereograms are produced using a three-step process in which a series of two-dimensional perspective views are prepared, a H.sub.1 hologram is prepared from the two-dimensional perspective views, and a H.sub.2 hologram is prepared from the H.sub.1 hologram. For the non-90.degree. case, the two-dimensional perspective views are oriented at an angle relative to the plane of the H.sub.1 hologram during the preparation of that hologram. Similarly, during the preparation of the H.sub.2 hologram for this case, the H.sub.2 hologram is oriented at an angle relative to the H.sub.1 hologram. In this way, the viewing slits generated by the holographic stereogram are located in the vicinity of the user's eyes for the non-90.degree. case as is desired.Type: GrantFiled: June 7, 1995Date of Patent: September 2, 1997Assignee: Polaroid CorporationInventors: William J. Molteni, William J. Volchok

Patent number: 5576853Abstract: Apparatus and methods are provided for mass production of transmission holograms onto a continuous web of photosensitive material, one method involving the mounting of a master transmission hologram onto the outside surface of a clear hollow drum, the clear hollow drum being rotatable and having means for directing an irradiating wavefront propagated from a radiation source through the master transmission hologram onto a passing recording medium in a predetermined direction, the directing means configured so that said predetermined direction is fixedly maintainable independent of the rotation of the hollow drum and the master transmission hologram mounted thereon. The redirected irradiating wavefront transmitted through the master transmission hologram generates an object beam and a "zero order" reference beam, said object beam and "zero order" reference beam combine to form an interference pattern, the interference pattern being recorded on the photosensitive recording medium.Type: GrantFiled: December 20, 1994Date of Patent: November 19, 1996Assignee: Polaroid CorporationInventors: William J. Molteni, Michael M. Wenyon
