Abstract

Establishment of a simple and reasonable technique and its application to the metallic surface in addition to the nonmetallic surface in the room-temperature measurement using infrared picture equipment have been studied. It was found, as published in the previous paper, in the investigation of radiation temperature, radiosity coefficient, their wave-length dependence and the dispersiveness of these parameters about the surfaces of various kinds of material that the assumption of gray body approximation does not hold in the surfaces of metal and part of nonmetal. In the present work, applicability of pseudo-gray body approximation to the metal surface in a system surrounded by black body surfaces was studied in consideration of directivity of emissivity and reflectance while, in actual, a measuring angle of 15 degrees giving a small directivity effect was used based on experimental results. As in the previous paper, three kinds of sensors different in the detectable wave-length range were used to evaluate the radiation temperature, emissivity, radiosity coefficient, and their dispersiveness. The experimental results proved the applicability of pseudo-gray body approximation. 3 refs., 18 figs., 2 tabs.
