2 DOF optical microscanner with large deflection angles
IEEE/LEOS International Conference on Optical MEMS and Their Applications Conference, 2005., 2005This paper reports on a novel microscanner with two degrees-of-freedom (DOF) fabricated from a shape memory alloy (SMA) thin film composite consisting of a three-layer system of Ti(Ni,Cu)/Mo/Fc(Cr,Ni). This three-layer system creates concave and convex curvatures upon heating and cooling, respectively, due to a strong change of bimorph stress mainly ...

Torsional Structures to Enable Large Angle Deflections
MEMS micromirrors for large angle beamsteering are needed for numerous broadband steering and imaging applications. However, current scanning micromirrors generally exhibit scanning angles (La Vern Starman, D. Torres, J. P. Walton

Trajectory Equations for Constant Tool Face Angle Deflections
IADC/SPE Drilling Conference, 1992ABSTRACT Prior to the introduction of steering tools and MWD survey equipment, all deflection tools produced circular arc deflections. In order to drill a circular arc deflection the directional driller must change the tool face angle during the course of the correction.
