A system ( 10 ) for imaging a combustion turbine engine airfoil includes a camera ( 12 ) and a positioner ( 24 ). The positioner may be controlled to dispose the camera within an inner turbine casing of the engine at a first position for acquiring a first image. The camera may then be moved to a second position for acquiring a second image. A storage device ( 30 ) stores the first and second images, and a processor ( 32 ) accesses the storage device to generate a composite image from the first and second images. For use when the airfoil is rotating, the system may also include a sensor ( 40 ) for generating a position signal ( 41 ) responsive to a detected angular position of an airfoil. The system may further include a trigger device ( 42 ), responsive to the position signal, for triggering the camera to acquire an image when the airfoil is proximate the camera.
