Step Height
"Step height" is an example of a two-channel measurement, where one displacement value is subtracted
from another.
Two probes can be used independently (without adding or subtracting displacement values) to analyze
displacement in one direction with respect to displacement in another direction. This relationship may be
displayed on an oscilloscope.
Velocity
The "surface velocity" of a measured object describes the rate at which the displacement measurement is
changing. This value is equal to the first derivative of displacement with respect to time.
Acceleration
The "surface acceleration" of a measured object describes the rate at which the surface velocity is chang-
ing. This value is equal to the second derivative of displacement with respect to time.
