Micromechanical Actuator With Asymmetrically Shaped Electrodes

US Patent:
7629725, Dec 8, 2009
Filed:
Apr 1, 2005
Appl. No.:
11/096395
Inventors:
Clifford F. Knollenberg - El Cerrito CA, US
Michael Albert Helmbrecht - Lafayette CA, US
Assignee:
Iris AO, Inc. - Berkeley CA
International Classification:
H02N 1/00
G02B 26/08
US Classification:
310309, 3592241, 359290
Abstract:
A micromachined actuator including a body or platform mounted to a suspension system anchored to a substrate. In one embodiment, the suspension system is comprised of a set of one or more spring flexures connecting the actuator body to the substrate with strain relief provided via connecting torsional elements. In another embodiment, the suspension system includes a first set of one or more spring flexures each with one end anchored to a largely rigid intermediate frame and the other end attached to the body. A second set of one or more flexures is attached between the intermediate frame and the substrate. A third actuator embodiment maximizes force electrode area to minimize voltage required for electrostatic actuation. A fourth embodiment provides electrical interconnect to an actuator or an actuator array using polysilicon with silicon nitride isolation. Actuators may be fabricated by combining the key features of all four embodiments or actuators may be fabricated using any combination of two or three of the embodiments.

Deformable Mirror Method And Apparatus Including Bimorph Flexures And Integrated Drive

US Patent:
2004016, Aug 26, 2004
Filed:
Nov 7, 2003
Appl. No.:
10/703391
Inventors:
Michael Helmbrecht - Lafayette CA, US
International Classification:
G02B026/08
US Classification:
359/223000
Abstract:
An apparatus comprising a substrate; and a platform elevated above the substrate and supported by curved flexures. The curvature of said flexures results substantially from variations in intrinsic residual stress within said flexures. In one embodiment the apparatus is a deformable mirror exhibiting low temperature-dependence, high stroke, high control resolution, large number of degrees of freedom, reduced pin count and small form-factor. Structures and methods of fabrication are disclosed that allow the elevation of mirror segments to remain substantially constant over a wide operating temperature range. Methods are also disclosed for integrating movable mirror segments with control and sense electronics to a produce small-form-factor deformable mirror.
