Existing methods to provide cable orientation and array element localization in the Navy’s fixed and towed array systems and tethered unmanned vehicles rely on devices embedded in the cable itself, such as hydrophones, magnetic heading and orientation sensors, and accelerometers. These traditional sensors have power, weight, space, and EMI budgets within the cable that require design compromises to be made and further increase the design complexity of the system. Luna has recently made advances in a break-through fiber optic shape sensing technology that is based on Optical Frequency Domain Reflectometry enabling accurate positional information at all points along a tether in an extremely small, lightweight, EMI-immune fiber optic package. In the proposed research effort we will further development of a concept designed to add another degree of freedom to the measurement system, which will significantly increase the accuracy of the shape measurement and is essential for applications where extrinsic twist may be imposed on the fiber. Luna will work with a leading University to extend analytical and FEA models of new fiber geometries and to conduct testing to quantify accuracies in relevant environments. During Option II Luna will demonstrate system performance to TRL3.
