A new spectrophotometer system is developed for the study on thermal radiation phenomena of real surfaces. This system can measure spectra of reflection and emission of radiation at 93 wavelength points in the near-ultraviolet through infrared region of λ=0.30〜11μm on one system simultaneously and repeatedly with a cycle time of 2s. The system is applied to investigate the transition of spectra of reflection and emission of a metal surface in a high-temperature air-oxidation process. It is demonstrated that interference and diffraction behavior, which is caused by the change in microstructure of the surface, is clearly observed as simple and systematic change of the spectra over the wide spectral region. The ability of the developed system for the study on radiation phenomena is demonstrated. It is also suggested that a real-time technique can be developed on the basis of the performance of the developed system to diagnose the temperature and microstructure of real surfaces.
