METHOD AND PRECISION NANOPOSITIONING APPARATUS WITH COMPACT VERTICAL AND HORIZONTAL LINEAR NANOPOSITIONING FLEXURE STAGES FOR IMPLEMENTING ENHANCED NANOPOSITIONING PERFORMANCE

摘要

An enhanced method and precision nanopositioning apparatus for implementing enhanced nanopositioning performance is provided. The nanopositioning apparatus includes a vertical linear nanopositioning flexure stage and a horizontal linear nanopositioning flexure stage. The vertical linear nanopositioning flexure stage includes a stage base, a symmetrically configured flexure linear guiding mechanism with precision motion enhancement structure, and a stage carriage. The horizontal linear nanopositioning flexure stage is mounted on the stage carriage of the vertical linear nanopositioning flexure stage, and includes a middle-bar relative position control mechanism to enhance the stiffness of a flexure linear guiding mechanism.
