What is a Piezo Flexure Stage?
A Piezo Stage can be characterized as a mechanical device, driven by a piezoelectric actuator, which provides one or more axis of motion.
Deciding Between Open-Loop and Closed-Loop Piezo Stages
The term “closed-loop” in nanopositioning indicates that a sensor is used to monitor the position of the stage in real-time. These readings feed back to the controller to provide error correction for the system. Closed-loop control ensures that the nanopositioner reaches the desired commanded position. nPoint uses interferometric calibration for each...
