  • Patent number: 8503054
    Abstract: A device for deflecting light beams is provided, which includes a swing-mounted light exit segment of an optical waveguide and a swing-mounted mirror. The device features a first rotation device that is set up to rotate the light exit segment of the optical waveguide, from which light is able to strike the mirror, in a rotational plane, and a second rotation device that is set up to rotate the mirror around a rotational axis situated in the mirror plane, which deviates from the vertical to the rotational plane.

  • Publication number: 20110279919
    Abstract: A method for manufacturing a micromechanical component is described, including the steps of: forming a first etch stop layer on a base substrate, the first etch stop layer being formed in such a way that it has a first pattern of through-cutouts; forming a first electrode-material layer on the first etch stop layer; forming a second etch stop layer on the first electrode-material layer, the second etch stop layer being formed in such a way that it has a second pattern of through-cutouts differing from the first pattern; forming a second electrode-material layer on the second etch stop layer; forming a patterned mask on the second electrode-material layer; and carrying out a first etching step in a first direction and a second etching step in a second direction counter to the first direction in order to etch at least one first electrode unit out of the first electrode-material layer and to etch at least one second electrode unit out of the second electrode-material layer.

  • Publication number: 20110261428
    Abstract: A micromechanical component has a light window; a mirror element adjustable with respect to the light window from a first position into at least one second position about at least one axis of rotation, an optical sensor having a detection surface designed to ascertain a light intensity on the detection surface and to provide a corresponding sensor signal. The light window, the mirror element in the first position and the detection surface are situated in relation to one another in such a way that a portion of a light beam reflected on the light window strikes the detection surface at least partially; and an evaluation unit designed to define, on the basis of the sensor signal, information regarding an instantaneous position of the mirror element and/or an instantaneous intensity of the deflected light beam.

  • Publication number: 20110260658
    Abstract: A method for operating an electrostatic drive having a stator electrode and an actuator electrode which are designed as multilayer electrodes having subunits includes: predeflecting the actuator electrode with respect to the stator electrode from its non-energized starting position into a first end position by applying a first potential to the first stator electrode subunit, and applying a second potential which is different from the first potential to the first actuator electrode subunit, and applying a third potential which is different from the first potential and the second potential, to the second stator electrode subunit and to the second actuator electrode subunit.

  • Publication number: 20110254404
    Abstract: An electrostatic drive is described having an inner frame, at least one intermediate frame, which encloses the inner frame, and an outer frame, which encloses the inner frame and the at least one intermediate frame, each two adjacent frames of the inner, intermediate, and outer frames being connected to one another via at least one spring element, the spring elements, via which each two adjacent frames of the inner, intermediate, and outer frames are connected to one another, being situated in such a way that the longitudinal directions of the spring elements lie on a common longitudinal spring axis, and electrode fingers being situated on frame bars, which are oriented parallel to the longitudinal spring axis, of the inner frame, the at least one intermediate frame, and the outer frame. A manufacturing method for an electrostatic drive, a micromechanical component, and a manufacturing method for a micromechanical component, are also described.

  • Publication number: 20110248601
    Abstract: A cascaded micromechanical actuator structure for rotating a micromechanical component about a rotation axis is described. The structure includes a torsion spring device which, on the one hand, is attached to a mount and to which, on the other hand, the micromechanical component is attachable. The torsion spring device has a plurality of torsion springs which run along or parallel to the rotation axis. The structure includes a rotary drive device having a plurality of rotary drives which are connected to the torsion spring device in such a way that each rotary drive contributes a fraction to an overall rotation angle of a micromechanical component about the rotation axis.
