A non-contact all-fiber optic acceleration measurement system has been proposed in this work. Using a fiber delay line in the fiber-optic path, the difference between two Doppler shifted frequencies of a laser beam corresponding to two different velocities of a moving object with a fixed time delay was measured and used for acceleration extraction. By performing acceleration measurements for a piezoelectric ceramic oscillator driven by an open-loop piezo controller at different voltages, a measurement error of better than -3.766% and nonlinearity degree of 0.314% were achieved.
