Zusammenfassung:A flash thermography device for generating an infrared image of a turbine component located inside a turbine. The device includes a flash enclosure having an aperture. A flash source is located in the aperture wherein the flash source generates a light pulse that heats the turbine component. The device also includes an infrared sensor for detecting thermal energy radiated by the turbine component wherein the radiated thermal energy is transmitted through the aperture to the infrared sensor to enable generation of an infrared image of the turbine component. Further, the device includes moveable arm that holds the flash enclosure and infrared sensor wherein the arm is inserted through an opening in the turbine to enable positioning of the flash source and infrared sensor in close proximity to the turbine component.
