Abstract

The construction and performance of a two-sensor fiber-Sagnac- based sensor array is reported. The array is constructed in a folded configuration which passively desensitizes the delay coil to phase modulations. Experimentally, the delay coil desensitization is measured to agree with predictions. The sensor phase sensitivity is measured to be as low as 3 (mu) rad/(root)Hz and 0.8 (mu) rad/(root)Hz in a single- detection and a balanced-detection configuration, respectively.
