Beschreibung
Zusammenfassung:	The invention relates to a system to prognose gas turbine remaining useful life. A flash thermography device for generating an infrared image of a turbine component located inside a turbine, wherein the turbine includes at least one inspection port. The device includes a flash source that generates a light pulse that heats the turbine component and an infrared sensor for detecting thermal energy radiated by the turbine component. The device also includes a borescope having a sensor end, a viewing end that includes the flash source and an interior hollow that extends between the sensor and viewing ends. The borescope is positioned in the inspection port such that the viewing end is located inside the turbine. Thermal energy radiated from the turbine component is transmitted through the hollow to the infrared sensor to enable generation of the infrared image. The device further includes a reflector located on the viewing end that directs the light pulse toward the turbine component and a flash power supply for
