The Principles of Accelerometers
In this chapter we consider acceleration measurement and examine the dynamic behavior of a common accelerometer, the mass-spring second-order model, describing its responses to an impulse and to a sustained periodic driving force. We will describe open-and closed-loop (servoed) instruments and the types of servos they can use. We will also mention the principles of two new accelerometers, the surface wave and fiber-optic types.
