摘要： A piezoelectric actuator with integrated features to provide coarse position adjustment of a pushing threaded rod and also mechanically amplified piezo motion for fine position adjustment is presented here in three design variants. The mechanical amplifier houses one or more piezo stacks in longitudinal axis with preload to translate an amplified motion in the order of a few times in the transverse axis, perpendicular to the piezo stack motion. The piezo amplifier output travel is transmitted to the threaded rod with a ball at the end to push a desired surface for position adjustments and motion translation in application such as a mirror mount.

摘要： Disclosed is an actuated, height adjustable optical table or workstation for use in microscopy, optical research laboratories and similar environments. The height adjustable design includes fixed and moving parts which combine to create a rigid, height adjustable table structure on which to mount an optical breadboard or similar platforms via optional rigid, passive or active vibration isolation mounts. The height adjustment is performed by multiple compact actuators with associated control hardware and software, and allows the user or an application system to perform activities with the table at any heights.

摘要： A piezoelectric actuator with integrated features to provide linear displacement of a threaded rod is presented. One mechanism provides mechanically amplified piezo motion for high speed/short travel position scanning whereas the other provides a low speed/long travel piezo motorized position adjustment. Mechanical amplifier incorporates one or more piezo stacks in longitudinal axis with preload to translate an amplified motion in the order of a few times in the transverse axis, perpendicular to the piezo stack motion. The piezo amplified output travel is transmitted to the internally threaded features of the other mechanism where a screw with a ball at the end to push a desired surface for high speed scanning mode translation. The internally threaded feature of the other mechanism is also operated by a secondary piezo stack which produces slip-stick motion steps to rotate the screw in one direction or the other to produce a slow speed/long travel mode.
