Publication number: 20230418071Abstract: A waveguide includes a waveguide body including an optically transmissive material having a refractive index different from a surrounding medium and defining an output surface. The waveguide body is configured to propagate light by total internal reflection in one or more directions substantially tangential to the output surface. The waveguide includes one or more diffractive optical elements (DOEs), each configured to change its diffraction efficiency in response to a respective stimulus, and a DOE driver configured to provide the stimuli to each of the DOEs independently.Type: ApplicationFiled: April 24, 2023Publication date: December 28, 2023Inventors: Juan Russo, Adam Douglas Greengard

Publication number: 20220404595Abstract: A projection lens can include four lens elements, each lens element being formed from glass and including spherical or planar incident and exiting surfaces. Compared to a projection lens that uses three lens elements, the four-element projection lens has relaxed manufactured and alignment tolerances. Unlike a projection lens that uses one or more plastic elements or uses aspherical surfaces, the all-glass projection lens can be manufactured using relatively fast and inexpensive grinding and polishing techniques. One or two of the glass lens elements can optionally be formed symmetrically, so as to be reversible. One glass element can optionally be plano-convex. A right-angle prism can direct light from a video display into the four glass elements. An achromatic prism can angularly divert the optical axis by about eight degrees and can direct light out of the four glass elements into a near-eye waveguide.Type: ApplicationFiled: July 1, 2022Publication date: December 22, 2022Inventors: Robert Matthew Bates, Adam Douglas Greengard

Patent number: 8610813Abstract: An optical system for generating an image having extended depth of field. The system includes a phase mask and a chromatic wavefront coding lens. The chromatic wavefront coding lens provides axial color separation of light by generating specified chromatic aberration in an image created by the lens. The phase mask causes the optical transfer function of the optical system to remain substantially constant within a specified range away from the image plane, and the optical transfer function of the system contains no zeroes within at least one spectral passband of interest. Digital processing may be performed on the image to generate a final image by reversing a decrease in modulation transfer function generated by the phase mask.Type: GrantFiled: May 31, 2011Date of Patent: December 17, 2013Assignee: OmniVision Technologies, Inc.Inventors: Lu Gao, Adam Douglas Greengard

Patent number: 7550701Abstract: Systems and methods reduce aberrations in a wavefront imaged by an optical system having a non-linear detector. A wavefront of electromagnetic radiation from an object imaged to the non-linear detector is encoded. Data from the non-linear detector is digitally converted to form a digital representation of the image captured by the non-linear detector. The detected image is linearized to form a linearized image. The linearized image is filtered to reverse effects of wavefront coding to form a final image.Type: GrantFiled: February 25, 2004Date of Patent: June 23, 2009Assignee: OmniVision CDM Optics, Inc.Inventors: W. Thomas Cathey, Jr., Adam Douglas Greengard
