A new running condition monitoring method of motors such as generator sets

and aircraft engines

using distributed fiber-optic sensor has been introduced.A Michelson Interferometer based fiber-optic sensor is constructed

which offers a high sensitivity of disturbance detection.Because the sensing arms of the sensor are composed of optical fiber

the distributed fiber-optic interferometric sensor provides a high capacity of anti-electromagnetic interference.The monitoring system has simple structure

and the sensor can be fixed on the motor easily to monitor its running condition.
