Paper Abstract

We proposed a novel intensity modulation based composite cavity optical fiber laser (CCFL) sensor, which is suitable for the vibration measurement. The intensity modulation of the CCFL is caused by the modulation of the weak feedback of the CCFL. The weak feedback of the CCFL is based on the end face reflection and the Rayleigh scattering of optical fiber. An acoustic measurement of the CCFL sensor in anechoic water pool is demonstrated to prove that the simple sensing scheme is feasible.
