Abstract: The invention relates to a device for detecting a flaw in a fibre-reinforced component, in particular delamination in a bearing region of a hole, by means of at least one probe, wherein an ultrasound field is emittable and detectable by means of the at least one probe. The ultrasound field is coupled according to the invention to the component at an angle of incidence ? of greater than 0° from a normal of an upper side of a component. The oblique radiation enables a higher degree of resolution to be achieved when detecting delamination in the bearing region of holes. Further variants of the device operate using at least one linear probe received in a self-positioning holder. The rotating linear probe is composed of a plurality of individual vibrator elements which are arranged at regular intervals behind one another.
