A theory of the influence of measurement conditions and system parameters on the accuracy of remote temperature measurements with thermal imaging systems has been developed. An analysis of the influence of disturbances (such as: incorrectly assumed emissivity, radiation reflected by the object, radiation emitted by the optics of the system, limited transmittance of atmosphere and limited temperature resolution of the system) on the accuracy of temperature measurement has been made. The results have shown that the accuracy clearly differs in 3-5J.lm and 8-12J.lm spectral band under typical measurement conditions. |
