The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Recent progress in the design of infrared-sensitive cameras makes it possible to discover and depict not only underpaintings and pentimenti, but entire paintings that were later overpainted by the artist. He was surprised at the result and called them "Calorific Rays". Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space such as molecular clouds, detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Art conservators use the technique to examine how the visible layers of paint differ from the underdrawing or layers in between (such alterations are called pentimenti when made by the original artist). Distant galaxies with a high redshift will have the peak portion of their spectrum shifted toward longer wavelengths, so they are more readily observed in the infrared. Effectively that's science nonsense, but I guess it sells well. [48], Strong infrared radiation in certain industry high-heat settings may be hazardous to the eyes, resulting in damage or blindness to the user. [5] Most of the thermal radiation emitted by objects near room temperature is infrared. A spectrum of all the frequencies of absorption in a sample is recorded. The LWIR (8–15 μm) region is especially useful since some radiation at these wavelengths can escape into space through the atmosphere. Cet exemple ne correspond à la traduction ci-dessus. A variety of technologies or proposed technologies take advantage of infrared emissions to cool buildings or other systems. However, black-body, or thermal, radiation is continuous: it gives off radiation at all wavelengths. This is a property of a surface that describes how its thermal emissions deviate from the idea of a black body. Thermal radiation can be emitted from objects at any wavelength, and at very high temperatures such radiation is associated with spectra far above the infrared, extending into visible, ultraviolet, and even X-ray regions (e.g. Elément de transfert thermique couleur comprenant un substrat sur lequel sont appliquées dans l'ordre suivant, (a) une couche de conversion de lumière en. The infrared channel, in combination with the other channels, is used to detect the location of scratches and dust.
