Surface temperature distribution measuring device and measuring method

摘要

PROBLEM TO BE SOLVED: To simultaneously measure surface temperature distributions in an outer peripheral direction of a measurement target object with a simple device.SOLUTION: There is provided an apparatus that receives infrared radiation light from a measurement target object 2 to measure the surface temperature of the measurement target object 2, and comprises one infrared thermal image device 11 and at least two or more infrared mirrors 12. The infrared thermal image device 11 directly receives infrared radiation light from a predetermined direct measurement rage on the surface of the measurement target object 2; the infrared mirrors 12 receive infrared radiation light from a range other than the direct measurement range on the surface of the measurement target object 2 and reflect the light toward the infrared thermal image device 11; and the infrared thermal image device 11 further receives the reflected light from the infrared mirrors 12.SELECTED DRAWING: Figure 1
