  • Abstract
    The design of an optical polarimetric imaging system, aimed at detecting cracks or structural defects on the surface of rotating aircraft engine shafts, is presented. The experimental results clearly indicate that high signal-to-noise ratio signals can be obtained, so that it minimizes the use of processing techniques.
