Abstract : Fiber-reinforced composite laminates materials can be affected by various defects. Focus is onto missing circular cylindrical fibers within an otherwise periodic system of fibers, assuming that proper data are collected from illuminations of the laminate, possibly in the near field of the structure. Imaging under various guises, with linear and non-linear models, one-shot or iterative solutions, is proposed and analyzed from a range of numerical simulations with emphasis on resolution level.
