    Optical Trapping of Large Metallic Particles in Air

    No full text
    In this paper, we introduce a horizontally-oriented, photophoretic `boat' trap that is capable of capturing and self-loading large (radius ≥1{\ge}1 μ\mum) solid gold particles in air for more than one hour. Once trapped, particles are held stably, even as the trap is modified to scan axially or expanded to a larger size to increase the capture cross-section. We theoretically present and experimentally demonstrate each of these affordances. We describe the utility of such to investigate large, metallic, and plasmonic particles for display applications

    BYU HoloMonitor Accommodation-Parallax Demo

    Taken by placing a video camera at the viewing plane of the monitor. A computed hologram is output, and the monitor is first rotated side-to-side, demonstrating parallax. Then, accommodation cues are shown as the camera is refocused to different depths
