Optimization of mirrors for the ultrasonic inspection of complex-shaped components using standard transducers

The inspection of components with complex shapes can suffer from the fact that the area of interest can not be properly insonified due to restricted access. In such cases the use of mirrors to turn the ultrasonic beam onto the component's surface has proven to be efficient. The optimization of such a mirror is addressed where its shape is designed to compensate the influence of the curved component surface on the ultrasonic beam field and to additionally achieve a focusing of the beam.
