Abstract:
1. A method for defect investigation of a component, comprising: acoustically irradiating a surface of the component obliquely, using a checking sound beam produced by a transmission/reception transducer, where the sound beam passes through a liquid or gaseous medium in which the component is immersed; receiving a response sound beam which is reflected back from the surface to the transmission/reception transducer; evaluating the response sound beam with respect to a signal runtime in the medium, taking into account the signal runtime in the medium between the transmission/reception transducer and the surface; and localizing a defect within the component by taking the signal runtime in the medium into account, the signal runtime in the medium and said localizing being alternately determined using at least one of an emission condition and/or at least one of a reception condition including:
