Overview of Piezoelectric Actuator Displacement Measurements Utilizing a MTI-2100 Fotonic Sensor

摘要

The MTI-2100 is a measurement system that provides for non contact precise measurement of the position, the displacement (micro-positioning), and the vibration of an object in planar motion. By using fiber optic technology, these measurements provide assistance to thoroughly understanding the structural dynamics of a planar actuating object. This report describes the operational principles of the MTI-2100 Fotonic(TM) Sensor measurement system. To illustrate how it works in practice the measurement system was used on a Pb(Zr0.55Ti0.45)O3 (PZT) bimorph driven flapping wing to measure flapping amplitude and frequencies.
