MEASURING DEVICE OF REFLECTIVITY OR TRANSMITTANCE OF ELECTROMAGNETIC WAVE AT HIGH TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a small-sized measuring device enabling measurement, for a wide range of incident angles and reflection angles, of the true reflectivity of a body itself relative to an electromagnetic wave at a high temperature without using a standard sample, and further enabling measurement of transmittance.;SOLUTION: This measuring device of a reflectivity or a transmittance of an electromagnetic wave at a high temperature is equipped with a heating means for irradiating a beam to at least either surface of the front and rear surfaces of a sample and heating it; a temperature measuring means for measuring the temperature of a heated portion of the sample; an electromagnetic wave irradiation means for irradiating an electromagnetic wave to the heated portion of the sample; and an electromagnetic wave detection means for detecting the electromagnetic wave reflected by the sample or the electromagnetic wave transmitted through the sample, which is installed circulatably on the outer periphery of the heating means around the sample. In the device, the electromagnetic wave detection means is circulated, while irradiating the electromagnetic wave to the heated portion of the sample, and the electromagnetic wave reflected by the sample or the electromagnetic wave transmitted through the sample is detected at each position on circulation.;COPYRIGHT: (C)2009,JPO&INPIT
