2D sparse ultrasonic NDE array designs would benefit from a real-time simulation package in which the array transducer parameters and inspection scenario were fully integrated to optimise the array design for a specific application. Importantly, this process is not straight-forward for many applications, due to the conflicting requirements of conventional array theory (inter-element spacing and element beam characteristics) and the physical demands of the inspection scenario (refraction at non-planar interface). A novel algorithm has been developed that allows extremely efficient calculation of the total time of flight of an acoustic ray through two layer media, taking into account the effects of refraction through a 3D surface. The approac...
