Robustness of shape reconstruction based on strain sensing with multicore fibers

This study evaluates the performance of shape sensing cables in the presence of fiber core failures, a critical issue in scenarios where cable replacement is impractical due to technological and economic constraints. The impact of core failure is quantified by comparing the uncertainty in key parameters, such as curvature and bending angle, between pristine and damaged cables through simulation studies. Results indicate that while core failure degrades performance, shape reconstruction remains achievable.
