Revision of Radiometry,We begin with some definitions employed in the quantitative measures of visible radiation, which will enable us to classify the orders of magnitude that we will encounter in our presentation.

Transmission by the Atmosphere,The atmosphere between the source of radiation and the detector is usually the cause of perturbation in measurement.

Optical Materials for the Infrared,In general, the propagation of an electromagnetic wave in a material medium affects the properties of both wave and medium. In particular, the wave amplitude may be modified by absorption or emission by the medium, the wave may be split by double refraction and the direction of propagation may be altered by scattering and diffraction.

Characterisation of Infrared Systems,Infrared receiver systems are generally used for the remote detection of thermal phenomena. They usually produce one-or two-dimensional images and have to satisfy a number of more or less stringent functional criteria.

Commonplace

Choosing the Spectral Band,Differential sensitivity and thermal contrast both depend on the choice of the spectral band used for each application. We now turn to the factors that affect this choice, and their relative importance in each case. They are:
