The inspection of complex-shaped components can suffer from the fact that the area of interest can not be properly insonified due to restricted access. The influence of curved component surfaces on ultrasonic beam fields can be controlled by using curved mirrors. Additionally a focusing of beam fields generated by commercial, unfocused transducers is possible, as has been demonstrated for a complex aero engine component. The presented approach is particularly useful since commercial off-the-shelf transducers can be applied rather than specifically designed probes. On the other hand, the specifically matched mirrors can usually be easily produced in the machine shop.
