Abstract
Abstract
A new vibration measurement scheme is developed with an intrinsic Fabry-Perot interferometer (IFPI) built by two enhanced Rayleigh backscattering dots fabricated by femtosecond laser inscription. The cavity length of IFPI is absolutely and real-timely demodulated by fast white light interferometer demodulation.
