Abstract

The measurement of vibration generally requires the determination of the displacement of a surface (from a mean position) as a function of time. The aim of the measurement is to determine the amplitude and frequency content of the vibration, or track the vibration. In many different systems the range over which these measurements are required can span several orders of magnitude. It is not unusual for a measurement system to be required to respond to vibrations over the range 1 Hz to 1 MHz, with amplitudes ranging from a few millimeters to a sub-ångström (1 × 10−10 m) making this a very demanding measurement.
