This article examines the assessment of information loss when a thermal imaging device generates a thermal image of the observed scene. Various technical, operational, and economic requirements for thermal imaging devices define the quality criteria by which the device will be evaluated based on the "pass/fail" principle. To verify the quality criteria of a thermal imaging device, reference scenes containing objects are used, each of which is used to monitor one of the thermal imaging device's parameters. One of the key quality criteria is the thermal signal characteristic, which allows for the assessment of information loss due to the nonlinearity of the thermal signal characteristic. Methods for approximating the thermal signal characteristic have been developed. It is shown that the computational complexity of estimating the losses introduced by the thermal imaging device components that generate the thermal signal characteristic can be significantly reduced by using a piecewise linear approximation method.

The results of this study can be used in testing thermal imaging devices.
