Paper Abstract

Fibre optic sensors are used to measure sample displacements caused by a mechanical device capable of 1-D motion. Test samples, composed of multilayered materials, are submitted to sinusoidal excitations by means of an electromagnetic driver. The driving platform, as well as several test points in the sample, are instrumented with fibre optic bundles that are both, conveying a controled amount of light, and receiving the reflected light from the driver and sample points, in order to establish their instantaneous position with time. The device can oscillate up to several kHz, and the position of test surfaces evaluated with a precision of 1.5 microns.
