STM Lateral Micropositioning: A Tool for Nanofabrication
… microscope (STM) has been fitted with a lateral micropositioning device in order to allow imaging of surfaces over a range of a few millimeters. The probe is mounted on a stage which uses the principle of piezoelectric inertial translation to produce a controlled stepping motion along two axes. …

Development of Novel Piezo-Driven Parallel-Kinematics Micropositioning Stages
… above problems, we proposed novel designs for micropositioning stages. The key idea is to build the stages based on parallel kinematic mechanisms (PKM) that are more suitable for micropositioning than their serial counterparts. In order to further improve their kinematic and dynamic …

Analysis and Design of Surface Micromachined Micromanipulators for Out-of-Plane Micropositioning
… can be used to position microcomponents: the XZ Micropositioning Mechanism and the XYZ Micromanipulator. The displacement and force relationships are presented. The devices were fabricated using surface micromachining processes and the resulting mechanisms were tested. A compliant XYZ …

Design and implementation of a fiber optic doppler optical coherence microscopy system for cochlear imaging
… and the construction of a novel alignment and micropositioning apparatus increases ease of use for the researcher performing the imaging. To enable precise measurements of tissue motion, a time domain DOCM approach is used, utilizing an acousto-optic modulator (AOM) based optical heterodyne …
