    • An improved micromachined structure used for beam scanners, gyroscopes, etc. includes a reference member (154, 54) from which project a first pair of axially aligned torsion bars (156, 56). A first dynamic member (54 or 52), coupled to and supported from the reference member (154, 54) by the torsion bars (156, 56), oscillates in one-dimension about the torsion bar's axis. A second dynamic member (52) may be supported from the first dynamic member (54) by a second pair of axially aligned torsion bars (56) for two-dimensional oscillation. The dynamic members (54, 52) respectively exhibit a plurality of vibrational modes each having a frequency and a Q. The improvement includes means for altering a characteristic of the dynamic member's frequency and Q. Coupling between dynamic members (54, 52) permits altering the second dynamic member's frequency and Q by techniques applied to the first dynamic member (54). Some techniques disclosed also increase oscillation amplitude or reduce driving voltage, and also increase mechanical ruggedness of the structure.
    • 用于束扫描仪,陀螺仪等的改进的微机械结构包括参考构件(154,54),第一对轴向对齐的扭杆(156,56)从该参考构件(154,54)突出。 通过扭杆(156,56)联接到参考构件(154,54)并由参考构件(154,54)支撑的第一动态构件(54或52)围绕扭杆的轴线在一维上振动。 第二动态构件(52)可以由第二对轴向对齐的扭杆(56)从第一动态构件(54)支撑以进行二维摆动。 动态元件(54,52)分别具有多个振动模式,每个振动模式具有一个频率和一个Q.改进包括用于改变动态元件的频率和Q的特性的装置。动态元件(54,52)之间的耦合允许改变 第二动态构件的频率和Q通过应用于第一动态构件(54)的技术。 所公开的一些技术还增加了振幅或降低了驱动电压,并且还增加了结构的机械耐用性。
