CALIBRATION OF FIBER OPTIC ACCELEROMETERS BY SHAKER BASED VIBRATION TEST SYSTEM

Torben R. Licht, Soren Andresen

Abstract

A unique type of fiber optic accelerometer based on wavelength modulation by the Bragg grating principle has been developed.<BR />Testing, characterization and calibration of such transducers represent a challenge since they are not readily compatible with conventional data acquisition platforms.<BR />To overcome this technical challenge a system based on a precision vibration exciter driven by a newly released vibration controller has been configured.<BR />With this system the optical transducer system can be tested and the frequency response determined.<BR />This shaker based vibration test system represents a very useful solution for testing any new accelerometer technology that is not directly compatible with conventional data acquisition platforms.
