摘要： The embodiments described herein include scanners that can provide improved scanning laser devices. Specifically, the embodiments described herein provide scanners with a modular construction that includes one or more separately formed piezoelectric actuators coupled to a microelectromechanical system (MEMS) scan plate, flexure structures, and scanner frame. Such modular scanners can provide improved scanning laser devices, including scanning laser projectors and laser depth scanners, LIDAR systems, 3D motion sensing devices, gesture recognition devices, etc.

摘要： A light detection and ranging system includes multiple scanning mirror assemblies to increase a receive aperture. The multiple scanning mirror assemblies are controlled to mimic the operation of one large scanning mirror. The multiple scanning mirror assemblies may be arranged in one-dimensional arrays or two-dimensional arrays. Two arrays of scanning mirror assemblies provide for scanning in two dimensions.

摘要： A light detection and ranging system includes synchronously scanning transmit and receive mirrors that scan a pulsed fanned laser beam in two dimensions. Imaging optics image a receive aperture onto an arrayed receiver that includes a plurality of light sensitive devices. Scanning mirror assemblies include stationary coils and MEMS devices with attached mirrors and permanent magnets.

摘要： A mechanically resonant system exhibits a resonant mode frequency response. A conductor is included on a resonant member within the mechanically resonant system. A current in the conductor causes a modification of the resonant mode frequency response when in the presence of a magnetic field. The modification of the resonant mode frequency response may include an offset in the natural frequency of the mechanically resonant system.

摘要： 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.
