Multispectral radiometric temperature measurement algorithm for turbine blades based on moving narrow-band spectral windows

This paper addresses the problem of inaccurate emissivity presets for multispectral temperature measurements of aero-engine turbine blades and proposes a narrow-band spectral window moving temperature inversion algorithm that does not rely on an assumed emissivity model. As the emissivity of the mea...
