Abstract: An electromechanical actuator includes an oscillation resonator having the shape of a rod. The oscillation resonator is divided by a dividing plane that is not parallel to the longitudinal direction of the oscillation resonator into a first resonator portion and a second resonator portion. At least the first resonator portion includes electromechanical means which, when activated, are configured to generate a 3-dimensional acoustic bulk wave are with a mode shape asymmetric with respect to the dividing plane.

Abstract: An electromechanical actuator includes a base part and an oscillation resonator having the shape of a rod. The electromechanical actuator further includes amount for mounting the oscillation resonator to the base part. The mount is configured to bear the oscillation resonator so as to be rotatable around an axis of the oscillation resonator rod relative to the base part. A driver member is mechanically coupled to the oscillation resonator. A slider or a rotator is configured to be moved by the driver member when the oscillation resonator is excited.

Abstract: A device for absolute distance measurement includes a first tunable light source for emitting a first wavelength light of a first tunable frequency modulated by a first modulating frequency and a second light source for emitting a second wavelength light of a second frequency modulated by a second modulating frequency. An optical coupler couples the first wavelength light and the second wavelength light into an interferometer cavity. An interferometer detector provides an interference measurement signal based on a detected interference pattern. A demodulator unit generates a first demodulation signal based on the interference measurement signal by demodulation with the first modulating frequency and a second demodulation signal based on the interference measurement signal by demodulation with the second modulating frequency. A computation unit computes an absolute distance by evaluating the first demodulation signal acquired during a sweep of the first tunable frequency and the second demodulation signal.
Abstract translation: 用于绝对距离测量的装置包括用于发射由第一调制频率调制的第一可调谐频率的第一波长光和第二光源的第一可调谐光源，用于发射由第二调制频率调制的第二频率的第二波长光 。 光耦合器将第一波长光和第二波长光耦合到干涉仪腔中。 干涉仪检测器基于检测到的干涉图案提供干扰测量信号。 解调器单元通过利用第一调制频率的解调产生基于干扰测量信号的第一解调信号，并且以第二调制频率通过解调产生基于干扰测量信号的第二解调信号。 计算单元通过评估在第一可调谐频率和第二解调信号的扫描期间获取的第一解调信号来计算绝对距离。
