Characterization of modal domain fiber optic sensors for vibration detection and suppression in flexible structures

摘要

The research demonstrated experimentally for the first time the inclusion of a modal domain optical fiber sensor as a strain sensor in a control system designed to damp vibrations in a flexible beam. The experimental work included in the design and development of in-line fiber modal control devices and was supported by an analysis of the complete system. This analysis included the development of a model of the modal domain sensor for control system design and a thorough analysis of the performance of the system under a variety of operating conditions. The results of this research were completely documented in the publications listed.
