Patent number: 11762333Abstract: Methods, apparatus, devices, and systems for reconstructing three-dimensional objects with display zero order light suppression are provided. In one aspect, a method includes illuminating a display with light, a portion of the light illuminating display elements of the display, and modulating the display elements of the display with a hologram corresponding to holographic data to diffract the portion of the light to form a holographic scene corresponding to the holographic data, and to suppress display zero order light in the holographic scene. The display zero order light can include reflected light from the display.Type: GrantFiled: September 17, 2021Date of Patent: September 19, 2023Assignee: Pacific Light & Hologram, Inc.Inventors: Kamran Qaderi, Stephen John Hart, Robert Alan Hess, Jonathan Seamus Blackley

Patent number: 11415937Abstract: Methods, apparatus, devices, and systems for displaying three-dimensional objects by individually diffracting different colors of light are provided. In one aspect, an optically diffractive device includes: first and second diffractive components and a color-selective polarizer therebetween. The first diffractive component is configured to diffract a first color of light in a first polarization state incident at a first incident angle with a first diffraction efficiency at a first diffracted angle, and diffract a second color of light in a second polarization state with a diffraction efficiency substantially less than the first diffraction efficiency. The color-selective polarizer is configured to rotate the second polarization state of the second color of light to the first polarization state.Type: GrantFiled: September 17, 2021Date of Patent: August 16, 2022Assignee: Pacific Light & Hologram, Inc.Inventors: Kamran Qaderi, Stephen John Hart, Robert Alan Hess, Jonathan Seamus Blackley
