We introduce a Mach-Zehnder interferometer whose optical path difference is controlled by a tunable optical delay line. Using the interferometer as a demodulator for fiber Bragg grating sensors, intensity-based measurement of dynamic strain with a wide range of 0/spl sim/1880 /spl mu/strain and 0/spl sim/1 kHz is experimentally demonstrated.
