<p>A scanning probe microscope (SPM) has a piezoelectric actuator-based tube scanner to which a probe is attached and which is moveable in three planes by the application of a voltage to the piezoelectric tube. A set of flexures flex with the displacement of the tube and strain gauges attached to the flexures measure the flex of the flexures to provide feedback as to the displacement of the tube during the scanning of an object. The strain gauges and flexures form a kinematic sensing frame or arrangement in which a single constraint is provided for each degree of freedom and in which the constraints are at least substantially orthogonal to one another.</p> |
