This paper reviewed techniques of vibration sensors, studied structure and working principle of phase modulated optical fiber vibration sensor, and designed a new structure of non-contact optical vibration sensor. Use this structure, expect accuracy of 0.1um can be obtained in the range of 1mm. At the same time, this system is simple, anti-interference ability, high reliability and ease of practical.
