Calculation of thermal contrasts and potentials of the infrared images in spectral ranges 3...5μm and 8...14μm at the availability and in the absence of counterradiation of the environment

摘要

The calculations (for two spectral ranges, used in thermal imagines: 3...5μm and 8...14μm of thermal contrasts and potentials of the infrared images of objects of observation (OO), were carried out both availability the counterradiation of the environment, and in the absence of the counterradiation. (The counterradiation is a radiation, falling on OO, from the sky, from the surface of the Earth and from surrounding subjects. It is supposed that OO temperature does not differ significantly from temperature surface of the Earth surface). Is shown that in the infrared image in viewed spectral ranges (unlike the images of these OO in a visual spectral range) always (both at availability of and in its absence the counterradiation disappearance of some local areas (LA) -
