Publication number: 20220083002Abstract: 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 at an incident angle, a portion of the light illuminating display elements of the display, 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 redirecting display zero order light away from the holographic scene to suppress the display zero order light in the holographic scene. The display zero order light includes reflected light from the display. The light includes a plurality of different colors of light.Type: ApplicationFiled: September 17, 2021Publication date: March 17, 2022Inventors: Kamran Qaderi, Stephen John Hart, Robert Alan Hess, Jonathan Seamus Blackley

Publication number: 20220082886Abstract: 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: ApplicationFiled: September 17, 2021Publication date: March 17, 2022Inventors: Kamran Qaderi, Stephen John Hart, Robert Alan Hess, Jonathan Seamus Blackley

In one aspect, an optical device includes: a first optically diffractive component including a first diffractive structure configured to diffract a first color of light having a first incident angle at a first diffracted angle, a second optically diffractive component including a second diffractive structure configured to diffract a second color of light having a second incident angle at a second diffracted angle, a first reflective layer configured to totally reflect the first color of light having the first incident angle and transmit the second color of light, and a second reflective layer configured to totally reflect the second color of light having the second incident angle. The first reflective layer is between the first and second diffractive structures, and the second diffractive structure is between the first and second reflective layers.Type: ApplicationFiled: September 17, 2021Publication date: March 17, 2022Inventors: Kamran Qaderi, Stephen John Hart, Robert Alan Hess, Jonathan Seamus Blackley
