EXPERIMENTAL-VERIFICATION OF A THEORY OF THE INFLUENCE OF MEASUREMENTCONDITIONS ON TEMPERATURE-MEASUREMENT ACCURACY WITH IR SYSTEMS

A theory of the influence of measurement conditions on temperature mea surement accuracy with infrared systems has been recently presented. A comparison study of the shortwave (3-5-mu m) and longwave (8-12-mu m) measuring IR cameras was conducted on the basis of this theory. The r esults of the simulations show that the shortwave systems in typical m easurement conditions generally offer better accuracy in temperature m easurement than do the longwave systems. Some experiments that use a c ommercially available IR camera were carried out to verify the theory. The results of these experiments and a discussion about the theory li mitations are presented.
