Test head and method for non-destructive testing

When inspecting materials for hidden internal flaws using ultrasound, technicians often struggle to balance the width of the sound beam with the precision needed to detect small defects. Traditional large sound-generating surfaces create powerful beams, but they are too focused to scan large areas efficiently. This invention solves that problem by introducing a special diffusion element directly into the ultrasonic probe. This component cleverly widens the opening angle of the ultrasound beam without sacrificing the power and coverage of a large sensor. As a result, the new probe makes non-destructive testing faster, more reliable, and capable of inspecting larger volumes of a material in a single pass.
