Zusammenfassung:Thermographic inspection of an internal component (28, 34) of power production equipment (20) by inserting an ultrasound energizer (74A) into an inspection portal of the equipment to contact an exterior of the component, and inserting a camera scope via a second portal into an interior (52, 54) of the component. A motorized drive (66) may mount on a pilot fuel port (58) of a gas turbine to move the scope robotically within a combustor (28) and transition duct (34). A distal camera housing (69) on the scope pivots (64) and contains an infrared camera with a lateral field of view (85) that rotates about an axis 78 by rotating (73) a distal mirror head (70) on the housing or by rotating (73′) the housing (69′). Circumferential sets of thermographic images are acquired by rotating the field of view and translating it along a navigation path in the component interior.
