  • Patent number: 8606376
    Abstract: A method of actuating a system comprising a movable component and an actuator configured to move the movable component comprises providing a control signal representative of a desired motion of the movable component. The control signal is supplied to one or more resonators. Each of the one or more resonators has a mode of oscillation representative of at least one elastic mode of oscillation of the system. The control signal is modified by subtracting from the control signal a signal representative of a response of the one or more resonators to the control signal. The actuator is operated in accordance with the modified control signal. Thus, undesirable elastic oscillations of the system which might occur if the system were operated with the original control system can be reduced.

  • Patent number: 8345260
    Abstract: A method of detecting a movement of a measuring probe provided between an objective lens adapted to image an object plane on a predetermined image plane and the object plane is disclosed. Additionally, a measuring instrument comprising an objective lens and a measuring probe is disclosed. An input beam of light is split into a measurement beam and a reference beam. The measurement beam is focused on a reverse focal plane of the objective lens such that the measurement beam is collimated by the objective lens. The collimated measurement beam is reflected at the measuring probe. The reflected measurement beam is directed towards the objective lens such that the objective lens focuses the reflected measurement beam on the reverse focal plane. The reflected measurement beam is collimated. The collimated reference beam and the reference beam are superimposed to form a superimposed beam and an interference between the reflected measurement beam and the reference beam is detected.

  • Patent number: 7642503
    Abstract: N pieces of gains Gi are sequentially and temporarily set in a control circuit (23), and a stylus (131) is brought in contact with a workpiece (W) for conducting a temporary measurement. At this time, a sensor detection signal output from a sensor detection circuit (21) is filtered by a filter (31) to take out only a frequency component corresponding to a frequency of hunting generated in a closed loop (L) including the control circuit (23). Gains Gj that do not generate hunting in the closed loop (L) are extracted, and the largest gain Gj is set in the control circuit (23) in view of enhancement in responsivity etc. of the measurement. Alternatively, by pressing the stylus (131) into the workpiece (W), a displacement signal indicating a pressing amount and a sensor signal output from a sensor (13) are measured in accordance with a measurement load applied to the stylus (131) to calculate a gain Gs? of the sensor (13) based on the two signals.

  • Patent number: 7159452
    Abstract: A touch sensor 10 having a stylus 12 with a tip 12A making contact with a test piece W has an operational control structure including an oscillator 3 which oscillates the stylus 12 in the axial direction; a detecting circuit 4 which detects changes of oscillation of the stylus 12; an adjustor unit 5 which removes noise added to an output signal from the detecting circuit 4; a fine motion mechanism controller 6 which controls the operation of a fine motion mechanism 21 in such a manner that the change of the quantity of state of the detection signal is maintained constant; and a PZT driver 7 which operates the fine motion mechanism 21. The measuring force during surface configuration measurement can be adjusted by adjusting an alternating signal to be applied to the touch sensor or by reducing the noise added to the detection signal without making modifications to a shape or structure of the touch sensor.
