Method and system for inspecting cooling holes of a turbine engine component

A method of imaging a turbine engine component having a first surface and second surface spaced from the first surface, and a plurality of holes with inlets formed in the second surface fluidly coupled to outlets formed in the first surface, the method comprising:

• determining at least one fluid frequency corresponding to at least one portion of the turbine engine component;
• determining, based on the at least one fluid frequency, at least one sampling frequency;
• pulsing fluid at the at least one fluid frequency through at least a portion of the plurality of holes of the turbine engine component;
• imaging, during the pulsing of the fluid, the at least one portion of the turbine engine component using a thermographic sensor that captures images at the at least one sampling frequency;
• and
• storing the images captured by the thermographic sensor.
