Abstract

Variety of factors interact to produce a signal, received by the infrared imaging or measuring instruments. Spectral relationships can be recognized mainly as result of numerical modeling or highly specialized measurements. This paper presents elaborated models and many examples of computer simulation that use typical examples of measuring devices based on the photon and thermal detectors, as well as chosen results of experiments. Methods of spectral optimization of the IR sensing devices which base on the spectral contrast coefficient and simple method of spectral characteristics approximation are proposed. The aim of this paper is to help in understanding spectral phenomena that occur during the measurements, particularly in outdoor conditions.
