A fiber optic sensor coil is wound from a length of optical fiber with the mid-point of the optical fiber at the mid-point of the innermost layer of the coil and subsequent layers of the coil each have alternating turns of the two sections of the fiber emanating from the mid-point. The layers of alternating turns are formed by first winding a portion of one segment in such a fashion that adjacent turns are spaced apart by a distance equivalent to the diameter of the optical fiber. The layer is completed by winding a portion of the other segment such that the turns of the other segment are disposed between adjacent turns of the one segment. The number of turns in adjacent layers are unequal such that the turns of a next layer are arranged in grooves formed between two adjacent turns of optical fiber in the previous layer.

Une bobine de fibre optique est bobinée sur la longueur de la fibre optique avec le centre de la fibre optique au milieu de la couche la plus à l'intérieur de la bobine et les couches subséquentes de la bobine ayant chacune leurs tours des deux sections de fibre émanant du milieu. Les couches des tours alternés sont formées en bobinant d'abord une partie d'un segment de façon à ce que les tours adjacents soient espacés par une distance équivalente au diamètre de la fibre optique. La couche est complétée en bobinant une partie de l'autre segment de façon à ce que les tours des autres segments soient disposés entre les tours adjacents du premier segment. Le nombre de tours des couches adjacentes est inégal de manière à ce que les tours d'une prochaine couche soient arrangés dans les sillons formés entre deux tours adjacents de fibre optique dans la couche précédente.
