    摘要: A method and system for mitigating undesirable motion of the optics of a camera are disclosed. The system can include a stage and snubber assembly for defining motion of the camera optics. The stage and snubber assembly can include a stage assembly having a stage to which the optics are attachable, at least one wing formed upon the stage, and a snubber assembly configured to cooperate with the wing(s) so as to limit motion of the stage substantially to the desired direction of travel of the camera optics.

    摘要: A structure and method for an optical switch is provided that includes providing sidewall electrodes with steerable micro-mirrors to position and control micro-mirror movement. The structure and method includes using the sidewall electrodes in conjunction with electrodes underlying a micro-mirror to sense capacitance present between a micro-mirror and underlying electrodes and/or sidewall electrodes, and driving the electrodes underlying the micro-mirror and the sidewall electrodes to move the micro-mirror into an angular position. The electrode structures and methods of driving them may be used in systems with closed loop feedback control to reduce transient mirror settling time and provide substantial immunity to system perturbations when micro-mirrors switch an optical signal from an input fiber to an output fiber of the optical switch, or when a micro-mirror is held at an angular position over long time scales.
