description	A method of inspecting a component located on a rotor rotating about an axis internal to a turbine. An elongated probe is provided defining a probe length and having a one-dimensional pixel array formed by a plurality of pixels extending single file along the probe length. The probe is positioned through an access port in a casing of the turbine. The rotor is rotated to move the component past the pixel array, and energy emitted from an image area defined by a line extending along the component is received at the pixel array. An intensity-based signal from each pixel in the pixel array is conveyed to a processor to convert the intensity-based signals to an intensity-based line image, and a succession of the intensity-based line images are converted into a cohesive two-dimensional digital image of the component.
