PROBLEM TO BE SOLVED: To achieve a highly useful high precision radiant heat sensor even with an extremely simple configuration. SOLUTION: (1) Because measurement is performed while exhausting heat from a light reception surface so that a temperature of the light reception surface for the radiant heat is kept equal to the temperature of a measurement environment, outflow of heat from the light reception surface to the surroundings of the incident side does not occur, thereby performing precise measurement. (2) A thermoelectric element is used for the measurement of a heat flow value. COPYRIGHT: (C)2008,JPO&INPIT
