What is Phase Lag and How to Measure It

Understanding phase lag is important when scanning at high speeds with piezo flexure stages. This article describes the phase relationship between the command signal and the stage response. The response is monitored using the internal (in this case capacitive) sensor. The bandwidth of a system is the key element to phase lag. Using control parameters […]

Components of a Nanopositioning System

Nanopositioning systems provide the opportunity to enable many advanced applications. Their use has spread from AFMs to optics and multiple new technologies. While selecting a system can be complex at times, there are three main components that work together to provide motion on the nanoscale. Each component will briefly be discussed and can be studied […]
