概要

論文の詳細を見る
A new high-speed spectrophotometer system is developed. This system measures spectra of emission and reflection of a wide spectral region from the near-ultraviolet to the infrared (0.32〜11 μm) in one measurement system simultaneously and repeatedly with a cycle time of 2 s. This system is applied to the investigation of radiation characteristics of a metal surface to verify the performance in radiation heat transfer science investigation. An algorithm of a new diagnosis technique for temperature and microstructure of real surfaces of metals is presented on bases of the new high-speed spectrophotometer system and an electromagnetic wave theory. Evaluated surface quantities are temperature T, emittance ε (directional emittance), reflectance R (directional/ specular reflectance for directional incidence), specular reflection ratio β of the surface system, average thickness d of the surface film and root-mean-square (rms) roughness σ of the film surface at each time t.
