Figure 4-10. The variations in the apparent force exerted by a surface on a probe as a
function of the actuator-imposed position of the probe relative to the surface. (Upper) The
probe spring is barely super-critical leading to a large compliance range; (Center) The
probe spring is extremely super-critical such that the indentation forces dominate
the approach forces; (Lower) Magnification of the center graph, showing that the peak
force is unaltered by the probe spring stiffness. Values are normalized using the
