Abstract

The optical fiber winding structure provides a long-distance data link for the optical fiber optic guided missile (FOG-M). Based on the stress analysis, we established a brand new theoretical model to calculate the strain distributed of standard optical fiber winding structure. An iterative formula is obtained, which can be used to calculate the axial strain of each layer in winding process. Calculation results show that strain decreases continuously layer by layerfrom the outside to the inside layers and gradually converges to a constant after a couple of layers. Using the distributed Brillouin optical time domain analysis (BOTDA) technology, the distributed strain of fiber winding structure in different layers is measured. Experimental results agree with theoretical calculation. This research may provide an important means for the optimization of fiber winding process in the future.
