Abstract: A method of imaging a turbine engine component with a first surface and a second surface that is spaced from the first surface. The turbine engine component includes a plurality of holes with inlets formed in the second surface or interior that are fluidly coupled to outlets formed in the first surface or exterior. The method includes determining at least one fluid frequency, determining at least one sampling frequency, and pulsing fluid through at least a portion of the interior of turbine engine component while imaging the turbine engine component.
