Paper Abstract

A vibration-displacement measurement system by tracking the phase variation of an optical fiber Michelson interferometer with an electronic feedback loop is presented. The measurement system includes an electronic feedback loop which is used to track the phase variation induced by the measured vibration-displacement and provides a sense of direction of the displacement simultaneously. The measurement system is designed to be capable of measuring vibration-displacement with frequencies up to 200Hz and the measurement resolution can reach 13nm.
