Abstract

A multi-parameters measurement technique that uses four-core fiber as the sensing element has been proposed and demonstrated. The four-core fiber act as a four-beam interferometer in which phase differences is a function of curvature, twisting angle, and the variation of temperature in the plane containing the cores results in the shift of the farfield interferometric grid pattern. The relationship between the far-field grid pattern shift and the multi-parameters has been established and the experimental results were also confirmed this.
