Low-crosstalk real-time monitoring of optical path length in multiple fibre sections using range-gated subcarrier interferometry.

A system capable of real-time high-resolution optical-path-length monitoring of multiple sections of optical fibre is described. The low crosstalk interrogation system relies on range-gated subcarrier interferometry and is operated under computer control. The system is attractive for long-gauge-length structural monitoring.
