Abstract
A fiber optic sensor is formed by providing a first mandrel section having a first longitudinal slot therein, placing a reference fiber within the slot and winding a sensing fiber around the first mandrel. The sensor includes a second mandrel section having a second longitudinal slot therein and a spacer between the first and second mandrel sections. The sensing fiber and the reference fibers are wound around the spacer, and then the reference fiber is placed in the second longitudinal slot. The sensing fiber is wound around the second mandrel section. The sensor may include additional mandrels and spacers to form additional sections. A plurality of sensing coils may be formed on each mandrel section.
