Patent number: 11947314Abstract: VHOEs with expanded acceptance angle ranges are described as well as various systems and methods for fabricating VHOEs with expanded acceptance angle ranges. The VHOE with expanded acceptance angle range may include two or more individual Bragg gratings. The two or more individual Bragg gratings have the same diffraction geometry but with shifted Bragg conditions. Having the same diffraction geometry means when light is incident on the VHOE including two or more individual Bragg gratings, the diffracted light from each of the Bragg gratings is co-linear or overlapping with the diffracted light from the other Bragg gratings. The Bragg condition for each of the Bragg gratings are shifted with respect to each neighboring Bragg grating by an amount up to the acceptance angle range of each individual Bragg grating.Type: GrantFiled: December 15, 2020Date of Patent: April 2, 2024Assignee: A9.com, Inc.Inventor: Arkady Bablumyan

Patent number: 11789265Abstract: A waveguide image combiner is used to transmit a monochrome or full-color image in an augmented reality display. The combiner uses multiple stacked waveguides, each having top and bottom substrates. The combiner also uses multiple pairs of incoupling and outcoupling VHOEs, which are sandwiched between the top and bottom substrates, to expand a first FOV and an image expander to expand the second or perpendicular FOV. This suitably provides an expanded FOV that offers a diagonal FOV?50°, a horizontal FOV?40 and a vertical FOV?25°. The combiner also delivers a large horizontal eye box up to 20 mm and a vertical eye box of 10 mm while maintaining high light efficiency of the real scene (e.g. >80%). The system is able to use a light engine based on broadband (10 nm????40 nm) LEDs and maintain a large horizontal field of view and high transmission of the real imagery.Type: GrantFiled: September 11, 2020Date of Patent: October 17, 2023Assignee: A9.com, Inc.Inventor: Arkady Bablumyan

Publication number: 20220373971Abstract: The present invention features new waveguide layouts for input, redirection (expansion), and output holograms that minimize cross talk between colors and allow all three colors to reside in a single waveguide. The use of multiple incoupling holograms that diffract different colors of light in different directions, or along different paths, through a waveguide substrate advantageously provides for a reduction of cross-talk between the colors of a holographic image. In a square-shaped design, red, green, and blue input and output holograms approximately overlay on top of each other. The green redirection hologram is laterally separated from the red and blue redirection holograms. Using this square-shape design, the light beams for the three colors are separated into two paths propagating from input to output holograms.Type: ApplicationFiled: May 21, 2021Publication date: November 24, 2022Inventors: Arkady Bablumyan, Chen Liang

Publication number: 20210080907Abstract: Reflection mode VHOEs are designed and fabricated for use in imaging and other applications that require high diffraction efficiency with minimal chromatic aberrations and astigmatism across the bandwidth. A single VHOE acts as a mirror to reflect light (0th diffraction order) at the specified wavelength(s) and bandwidth with a principal ray at an angle equal to an angle of incidence of broadband light. A composite VHOE includes a complementary pair of input and output VHOEs each configured to diffract light into a non-zero Nth order. The input and output VHOEs are positioned in parallel to and offset from each other such that the filtered Nth order beam exits the composite lens on a path at the angle of incidence and parallel to the broadband light while suppressing the unwanted 0th order beam. The composite lens improves suppression of unwanted wavelengths while still achieving minimal chromatic aberration.Type: ApplicationFiled: November 24, 2020Publication date: March 18, 2021Inventors: Arkady Bablumyan, Lloyd J.

Patent number: 10871601Abstract: Transmission and reflection mode VHOEs are designed and fabricated for use in imaging and other applications. These VHOE provide high diffraction efficiency with minimal chromatic aberrations and astigmatism across the bandwidth. The lens provides optical power within the bandwidth centered relative to several wavelengths to magnify (focus or collimate) input light and is transparent for the rest of the image spectrum. In transmission mode, two VHOE are fabricated in such a way as to introduce compensating adjustments that minimize the astigmatism and chromatic aberrations introduced by the bandwidth of the input light. Two VHOEs are required to provide an on-axis imaging system to magnify light to form an image and reduce the chromatic aberrations across the bandwidth and reduce the astigmatism while maintaining high diffraction efficiency (DE).Type: GrantFiled: September 29, 2017Date of Patent: December 22, 2020Assignee: TIPD, LLCInventors: Arkady Bablumyan, Lloyd J.

Patent number: 8334889Abstract: A holographic direct-view display system uses holographic integral imaging techniques that is an auto stereoscopic way to reproduce parallax and occlusion. The display is not resolution limited and is scalable to display life size images if desired. The system can be used to transmit 3D depictions of a scene at video and sub-video rates as well as other information, such as images of documents or computer generated images. The images may be captured, transmitted and displayed in real-time (or near real-time) for telepresence or stored for time-shifted display. The system combines integral holography, a pulsed laser to record the hologram at high speed and a dynamic refreshable holographic material such as a photorefractive polymer as a recording media. The system uses techniques to write, read and erase the updateable hologram that allow the holographic material, hence direct-view display to remain stationary throughout each of the processes for continuous presentation of the hologram to the audience.Type: GrantFiled: November 26, 2010Date of Patent: December 18, 2012Assignees: TIPD, LLC, The Arizona Board of Regents on Behalf of the University of ArizonaInventors: Pierre-Alexandre Jean Blanche, Arkady Bablumyan, Nasser N.

Patent number: 8325402Abstract: A system and method that synchronizes a spatial light modulator (SLM) with a pulsed laser to record a hologram at the repetition rate of the pulsed laser for applications including holographic displays and data storage. The color channel capability of a SLM is utilized to effectively increase the write throughput when the pulsed laser repetition rate LR exceeds the SLM's image refresh rate R. The hogels are encoded on the color channels and concatenated to form a sequence of color images such that the write throughput is equal to the repetition rate LR up to a maximum of N*R. This effectively extends the capability and continued viability of existing inexpensive SLMs.Type: GrantFiled: February 15, 2010Date of Patent: December 4, 2012Assignees: TIPD, LLC, The Arizona Board of Regents on Behalf of the University of ArizonaInventors: Pierre-Alexandre Jean Blanche, Arkady Bablumyan, Nasser N.
