Positional Sensor Measures Rotational and Lateral Displacements

Positional sensors have applications where a very accurate measurement of position is needed over a limited range. One example of such an application is in manipulation of a stage of a high-resolution microscope such as an electron microscope. Electron microscopes include scanning electron microscopes (SEMs), transmission electron microscopes (TEMs), scanning transmission electron microscopes (STEMs), and various kinds of reflection and emission electron microscopes.
