NONCONTACT MEASURING METHOD OF SURFACE TEMPERATURE OF SAMPLE TO BE NATURALLY OR ARTIFICIALLY EXPOSED AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To enhance the accuracy of surface temperature measurement for a sample for evaluation of deterioration with time depending on exposure of the sample when the sample is naturally or artificially exposed.;SOLUTION: A holding frame 2 is rotatably mounted on the circumference of a xenon radiation source 4 within an exposing chamber 1, and the xenon radiation source 4 is located on a cylinder or a rotating shaft, and a filter 5 is provided around it. The sample 3 to be exposed is fixed within the holding frame 2, and exposed to the radiation from the xenon radiation source 4. The surface temperature of the sample 3 is directly recorded by a black body radiation detector such as a pyrometer 6 turned to a fixed area of the space through which the sample 3 periodically passes during rotation. The surface temperature is calculated from the detected black body radiation in an evaluation circuit with an emissivity stored for a different sample 3.;COPYRIGHT: (C)2005,JPO&NCIPI
