A Method for inspecting a component includes exiting a number of transducers forming
an array to produce an ultrasonic transmission beam focused into the component.
The array and the component are separated by a standoff. A Number of echo signals
are generated using the transducers, and the echo signals are processed in a number
of channels. The processing includes both dynamical focus and providing a dynamic
aperture on receive, both of which compensate for refraction of the beam at the
component / standoff interface. A single-turn inspection method includes :

Processing the echo signals to form at least one processed echo
signal. |
