摘要：
A flash thermography device for generating an infrared image of each of a plurality of rotating turbine components located inside a turbine. The device includes an infrared sensor for detecting thermal energy radiated by each component. The device also includes a borescope having a viewing end located on a longitudinal axis of the borescope. The borescope is positioned in an inspection port to locate the viewing end inside the turbine such that at least one component is within a field of view of the viewing end. In addition, the device includes a flash source that generates a plurality of light pulses corresponding to the number of components that rotate during a single rotation of the rotor, wherein the light pulses are oriented substantially transverse to the longitudinal. Thermal energy radiated from each component is transmitted through the borescope to the infrared sensor to enable generation infrared images.
