A method for the calibration of measuring instruments for the quantitative infrared radiation measurement

摘要

A method for the calibration of measuring instruments for the quantitative infrared radiation measurement, characterized in thata two-dimensional temperature distribution of the radiating surface of a calibrating radiator (1) is quantitatively measured,from this, a two-dimensional distribution of the radiant flux of the emitter surface is determined,the radiant flux depends on the measuring device (13) to be calibrated area is limited, andthe localised radiant flux with the two-dimensional, relative sensitivity in the field of view of the measuring instrument (13) is weighted and then, as a true density in the calibration method is used.
