Abstract

A two-beam interferometer is proposed and experimentally demonstrated with OPD magnified. Two cascaded fiber ring resonators with almost the same fiber length are spliced into a fiber loop. An acousto-optic modulator is employed to generate optical pulses and to choose the pulses traveling around one of the resonators for x trips. The interferometer is characterized in displacement in our experiment. Experimental results show the proportional relationship between the sensitivity and x. The high-sensitivity interferometer scheme is useful in some measurement applications that require high sensitivity, such as solid earth tide gauge.
