Infrared(IR) microspectroscopy could be defined as the coupling of a microscope to an infrared spectrometer. This coupling allows one to focus IR [infrared] radiation onto the sample, to collect and image transmitted or reflected IR radiation from the sample onto a detector, and to view and position the sample.  3, record 1, English, - infrared%20microspectroscopy

Remote Sensing is the science and art of acquiring information(spectral, spatial, temporal) about material objects, area, or phenomenon, without coming into physical contact with the objects, or area, or phenomenon under investigation.... In remote sensing, information transfer is accomplished by use of electromagnetic radiation(EMR). EMR is a form of energy that reveals its presence by the observable effects it produces when it strikes the matter.... Types [of remote sensing] in respect to the type of energy resources. Passive remote sensing makes use of sensors that detect the reflected or emitted electro-magnetic radiation from natural sources. Active remote sensing makes use of sensors that detect reflected responses from objects that are irradiated from artificially-generated energy sources, such as radar....

Satellite derived remote sensed images are representations of the variation in intensity of electromagnetic energy reflected from the Earth's surface. The specific image produced is determined by the wavelength of the electromagnetic energy that is being sensed, and the physical properties of the matter that reflects the energy. Aerial photographs use only the visible portion of the electromagnetic spectrum(5 x 107 metres=. 5 microns), whereas Landsat TM and SPOT images record the Earth's reflectivity at seven different wavelengths in the visible and infrared range, and radar images record the reflectivity of wavelengths in the non-visible range of 1 to 10 cm(microwaves).  3, record 10, English, - infrared%20band

Une composition en couleurs vraies ne pourra jamais rendre que l'information enregistrée pour les bandes bleues, vertes et rouges. Cependant, la plupart des satellites sont équipés de capteurs qui sont également sensible à des types de lumière invisibles pour l'homme (comme par exemple la lumière infrarouge ou ultraviolette). [En] bande infrarouge [..] tout comme pour les autres types de lumière, le capteur mesure la lumière infrarouge de chaque pixel. Pour chaque pixel, un nombre donné correspond à la lumière infrarouge. Plus le nombre est élevé, plus la proportion de lumière infrarouge mesurée est importante. Ainsi, les nombres mesurés pour l'eau par le satellite seront radicalement différents des nombres se rapportant aux forêts. De même, les prairies réfléchissent des quantités de lumière infrarouge différentes de celles réfléchies par les forêts, même si leur couleur (le vert) est identique. Lorsque nous transposerons ces nombres en images via l'ordinateur, la couleur des prairies sera différente de celle des forêts.

Optical remote sensing makes use of visible, near infrared and short-wave infrared sensors to form images of the earth's surface by detecting the solar radiation reflected from targets on the ground. Different materials reflect and absorb differently at different wavelengths. When solar radiation hits a target surface, it may be transmitted, absorbed or reflected. Different materials reflect and absorb differently at different wavelengths. The reflectance spectrum of a material is a plot of the fraction of radiation reflected as a function of the incident wavelength and serves as a unique signature for the material.  1, record 12, English, - reflectance%20spectrum

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead].  2, record 13, English, - laser%20velocimeter
