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.

Abstract: A microelectromechanical systems (MEMS) device includes a scanning platform suspended from a fixed platform by two flexures that form a pivot axis. The two flexures may be symmetric or asymmetric about a centerline of the scanning platform. At least one flexure includes two segments that are not parallel to each other. A second flexure may include two segments with one segment being wider than the other. Flexure design reduces effects of mounting and thermal stresses when the MEMS device is mounted as part of an assembly.

Abstract: The embodiments described herein provide microelectromechanical system (MEMS) scanners with increased resistance to distortion in the mirror surface. Such MEMS scanners, when incorporated into laser scanning devices, are used to reflect laser light into a pattern of scan lines. Thus, by reducing distortion in the scanning surface these MEMS scanners can provide improved performance in scanning laser devices, including scanning laser projectors and laser depth scanners. In general, this is accomplished by providing a MEMS scanner where the connection to the scan plate is made at an intermediate support structure, and at a point on that intermediate support structure that is offset from the scanning surface. Providing the connection to the scan plate at points offset from the scanning surface can reduce the distortion that occurs in the scanning surface as a result of rotational forces in the MEMS scanner.

Abstract: The embodiments described herein provide scanners with a modular construction that includes a separately formed scan plate coupled to a microelectromechanical system (MEMS) flexure structure. Such modular scanners, when incorporated into laser scanning devices, reflect laser light into a pattern of scan lines. In general, the modular scanner includes a scan plate that is formed separately from the flexure structure. The scan plate and flexure structure each include coupling features that serve to couple the scan plate to the flexure structure. The flexure structure includes flexure arms that facilitate rotation of the scan plate to reflect laser light into a pattern of scan lines.
