Abstract: A novel multiplexed optical sensor permitting absolute length measurement in remote reflective sensor arrays is proposed. Based on optical low-coherence reflectometry, this technique has been used to demonstrate length measurements to within 10 microns for 6 meter sensor cables situated 70 km from the receiver.
