Publication number: 20230050198Abstract: A near-eye display system that employs a volume holographic element containing distinct but overlapped planar volume gratings, each corresponding to a subset of pixels in the display. The volume gratings are illuminated using light incident from angles, and at wavelengths, that match the conical diffraction conditions for each grating, thereby achieving both high diffraction efficiency and a wide field of view. A single volume grating can thus be used to display thousands of pixels independently with high efficiency.Type: ApplicationFiled: January 20, 2021Publication date: February 16, 2023Inventors: Stephen P. McGrew, Elliot Burke, Robert J. Schultz

Patent number: 9065254Abstract: Embodiments of the invention describe an illuminator having a light source to originate an illumination beam, wherein the light source further comprises a set of vertical-cavity surface emitting lasers (VCSELs), including a first VCSEL having a first laser emission wavelength, and a second VCSEL having a second laser emission wavelength different than the first laser emission wavelength. Thus, by varying laser emission wavelengths of VCSELs in a VCSEL array, embodiments of the invention produce low-contrast speckle, and do not limit the imaging capabilities of the host illumination system. In some embodiments of the invention, vertical external cavity surface emitting lasers (VECSELs) are utilized to produce the above described varying laser emission wavelengths.Type: GrantFiled: June 2, 2014Date of Patent: June 23, 2015Assignee: FLIR Systems, Inc.Inventors: Jonathan Geske, Chad Wang, Elliot Burke

Patent number: 8698705Abstract: A compact near eye display generates image segments for a first dimension of an intended image. Each of the image segments is transformed into angularly distinguished beamlets that converge through a first dimension pupil within an eyebox. A scanning optic angularly separates the angularly distinguished beamlets of different image segments for creating a second dimension pupil. The angularly distinguished and separated beamlets propagate along a waveguide in a form that minimizes the thickness of the display in front of a viewer's eye and limits the overall size of the optics required to support the projection of virtual images into the viewer's eye.Type: GrantFiled: December 4, 2009Date of Patent: April 15, 2014Assignee: Vuzix CorporationInventor: Elliot Burke

Patent number: 8059342Abstract: A display platform orients a virtual image in alignment with a viewer's eye. A transmissive plate receives a light beam conveying the virtual image into the transmissive plate for propagation by internal reflection between inner and outer surfaces of the transmissive plate along the length of the transmissive plate. A plurality of reflective facets progressively interrupt the propagation of the light beam along the length of the transmissive plate for reflecting successive portions of the light beam in a direction for rendering the virtual image visible to the viewer.Type: GrantFiled: April 3, 2009Date of Patent: November 15, 2011Assignee: Vuzix CorporationInventor: Elliot Burke
