  • Scanning platforms for scanning laser devices
    Patent number: 9759909
    Abstract: Scanning platforms for use in scanning laser devices are described herein. These scanning platforms are particularly applicable to scanning laser devices that use microelectromechanical system (MEMS) structures to facilitate mirror motion. The scanning platforms include a centrally located stationary mount portion and a movable portion that surrounds the stationary portion. The movable portion is configured to be coupled to a mirror and to facilitate motion of that mirror. Such a scanning platform can facilitate reduced size in scanning mirror assembly, and thus can facilitate a more compact scanning laser device.

  • Scanned beam display having a redirected exit cone using a diffraction grating
    Patent number: 8579443
    Abstract: Briefly, in accordance with one or more embodiments, a scanned beam display, comprises a light source to generate a beam to be scanned and a scanning platform to scan the beam into an exit cone. The scanning platform receives the beam at a selected feed angle, and the scanning platform has a surface structure to redirect the exit cone at an exit angle that is less than the feed angle.
