摘要

A 3-component (3-C) fiber-optic accelerometer suitable for well logging is presented. The accelerometer can accomplish the 3-C measurement by multiplexing three unidirectional sensing elements which are based on a push-pull mass-spring structure. Experimental results show good linearity, consistency and stability. The suitable measurement frequency range of the system is between 3 and 800 Hz. The on-axis sensitivity, cross-sensitivity and minimum detectable level are 39 dB re rad/g, 14 dB re rad/g and 39.3 μg/Hz~(1/2), respectively.
