摘要：
The self-mixing sensing technique is a compact sensing technique that can be used for measuring distances, displacements, velocities, and vibration. In this letter, for good sensitivity remote measurement, self-mixing interference using an Er3+-Yb3+ Distributed Bragg Reflector (EYDBR) fiber laser is proposed and investigated for the first time. Results demonstrate that the EYDBR fiber laser presents a powerful tool for the self-mixing sensor and provides a remote measurement of the displacement and the vibration up to 20 Km.
