Abstract
In one embodiment, a system includes a multi-spectral pyrometry system configured to receive a broad wavelength band radiation signal from a turbine component, to split the broad wavelength band radiation signal into multiple narrow wavelength band radiation signals, to determine emissivity of the turbine component based on the narrow wavelength band radiation signals, and to detect spall on a surface of the turbine component based on the emissivity.
