There are two available contact-scanning technologies: passive and active. Passive scanning probe heads use springs to hold the stylus in its neutral position and strain gauges to measure deflection as it is moved by contours of the surface being measured. Active scanning probe heads use software-controlled electromagnets and force controllers in place of springs and strain gauges.
