<P>PROBLEM TO BE SOLVED: To provide a thermal emissivity measuring apparatus capable of measuring thermal emissivity accurately and easily. <P>SOLUTION: A thermal emissivity measuring apparatus comprises: a radiation sensor which is installed at a position isolated from the surface of a sample by a prescribed distance and can measure only thermal energy by thermal radiation incident on the incidence plane from the sample excluding thermal conduction and thermal convection; a heating part which heats the sample; a first temperature measurement part which measures the temperature of the sample; and a second temperature measurement part which measures the temperature of the radiation sensor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
