Abstract
Apparatus and method for temperature mapping a rotating component () in a high temperature combustion environment. The apparatus includes a thermal imager () having a field of view to sense infrared (IR) emissions. Emissivity of a surface of the component is subject to variation in the combustion environment. A radiance emitter () defines a spot within the field of view of the thermal imager. The spot indicates a respective emissivity value. A processor () is connected to the thermal imager to generate a radiance map of the component based on the IR emissions from the component. The processor includes a thermal calibration module configured to calibrate the radiance map based on the emissivity value of the spot within the field of view of the thermal imager to generate a calibrated thermal map of the component that displays absolute temperature over the surface of the component.
