abstract = "Dynamical sensing of strain via discrete reflectors interrogated by optical frequency domain reflectometry is described and demonstrated experimentally. The benefits of using discrete reflectors rather than Rayleigh back-scattering for dynamical measurements are elaborated. The method is tested in a sensor arm made from four discrete fiber segments of different lengths and in a fiber with an array of ten fiber Bragg gratings with the same center wavelength and ∼0.5% reflection. Dynamical sensing of oscillatory strain at 100 Hz, with absolute stretching amplitude <100nm, at ∼1km is demonstrated.",
