Claim Text:
1. A method of inspecting a component located on a rotor rotating about an axis internal to a turbine, comprising: providing an elongated probe defining a probe length and having a one-dimensional pixel array formed by a plurality of pixels extending single file along the probe length; positioning the probe through an access port in a casing of the turbine; rotating the rotor to move the component past the pixel array; receiving at the pixel array energy emitted from an image area defined by a line extending along the component and lying in a plane extending parallel to radial and axial directions in the turbine; conveying an intensity-based signal from each pixel in the pixel array to a processor to convert the intensity-based signals to an intensity-based line image; and converting a succession of the intensity-based line images into a cohesive two-dimensional digital image of the component.
