A novel distributed interference fiber optic sensor system for long distance measurement is proposed based on Machelson interferometer using a modulated laser (Frequency modulated continuous wave). By incorporating an optical loop with a frequency shifter in the reference optical path of Machelson interferometer, the measurement range of the sensor system has been increased 4 times and reached 48 meters.
