Abstract
We introduce a folded configuration of a previously described Sagnac interferometer-based sensor array. It is shown that the folded configuration lessens the detrimental effects of distributed phase modulations in the delay coil while also reducing the required delay coil length by a factor of 2. A prototype two-sensor array was constructed and measured to perform according to theory, exhibiting a phase sensitivity of roughly 3μrad/Hz in a single-port detection configuration and 0.8μrad/Hz in a balanced detection configuration. The desensitization of the delay coil was measured to agree with theory.
