Genesis of the scanning laser ophthalmoscope.... In the scanning device, the illumination is incident on a small spot of the fundus for a short time period, the illumination beam is displaced to the adjacent small spot, and this continues until the field of view of the fundus is covered. Simultaneously, with the spot of illumination, the scattered light is detected; the accumulation of all of the light from all of the illuminated spots forms the image of the fundus as seen on the display of the scanning laser ophthalmoscope.  7, record 1, English, - scanning%20laser%20ophthalmoscope

Atomic-force microscopy is similar to scanning-tunneling microscopy(STM) in that it can image surfaces at atomic-scale resolution. The difference between AFM and STM is that AFM does not require that the sample be an electrically conducting material. Like STM, it uses an atomically-sharp tip that is brought very close to the surface. The tip will feel a chemical attraction or repulsion and will move up or down on its supporting cantilever. This movement is monitored by an optical laser beam as the tip is moved laterally across the surface. As in STM, rastering the tip across the surface produces a topographic map of the surface.  3, record 13, English, - atomic%20force%20microscopy

La microscopie à force atomique (AFM : «atomic force microscopy») a été introduite en 1986 par G. Binnig, C.F. Quate et C. Gerber, comme une application du concept de microscope à effet tunnel (STM : «scanning tunneling microscope») [...] permettant l'étude de surfaces de matériaux isolants à l'échelle atomique. En combinant les principes du microscope à effet tunnel et du stylet profilométrique, les auteurs démontraient la possibilité d'imager, à l'air libre, la surface d'échantillons conducteurs ou non, avec une résolution latérale de 30 Å [angström] et une résolution verticale inférieure à 1 Å. La technique a, depuis lors, été adaptée à différents environnements tels que le vide, le milieu liquide, les basses températures, les champs magnétiques et aussi pour des applications en chimie ou en biologie. L'AFM est basée sur la mesure des forces entre un fin stylet et la surface étudiée. Le capteur de force est un ressort-lame (stylet) encastré à une extrémité et muni d'une pointe à l'autre extrémité; il est encore appelé «cantilever». Les forces d'interaction modifient la déflection ou la torsion statique ou oscillante du stylet. La mesure des déformations du «cantilever» dans les microscopes de force actuels s'effectue, le plus souvent, grâce à la déviation d'un faisceau lumineux («diode laser») réfléchi par l'extrémité du stylet, méthode proposée dès 1988 par G. Meyer et N. Amer [...] La majorité des utilisateurs cherche à obtenir des formes ou des tailles caractéristiques de la surface; en balayant l'échantillon sous le «cantilever», on obtient l'image AFM recherchée. Mais on s'est très vite aperçu qu'il était possible avec le même instrument de proposer des situations originales de «physique au nanomètre».  5, record 13, French, - microscopie%20%C3%A0%20force%20atomique

Scanning transmission electron microscopy(STEM) combines the principles of transmission electron microscopy and scanning electron microscopy and can be performed on either type of instrument. Like TEM [transmission electron microscopy], STEM requires very thin samples and looks primarily at beam electrons transmitted by the sample. One of its principal advantages over TEM is in enabling the use of other signals that cannot be spatially correlated in TEM, including secondary electrons, scattered beam electrons, characteristic X-rays, and electron energy loss. Like SEM [scanning electron microscopy], the STEM technique scans a very finely focused beam of electrons across the sample in a raster pattern. Interactions between the beam electrons and sample atoms generate a serial signal stream, which is correlated with beam position to build a virtual image in which the signal level at any location in the sample is represented by the gray level at the corresponding location in the image. Its primary advantage over conventional SEM imaging is the improvement in spatial resolution.  3, record 21, English, - scanning%20transmission%20electron%20microscopy

A confocal laser scanning microscope is a light microscope having a dramatically higher axial resolution than a conventional microscope. In other words, a confocal microscope is capable of optical sectioning. This is accomplished by illuminating the specimen one point at a time with a focused laser beam and using an optical arrangement, where only the light originating from the focus can be detected. The image is formed by scanning the laser beam over the specimen and recording the image into computer memory. A three-dimensional view of the specimen can be reconstructed from a stack of such images taken at successive focal planes.  2, record 24, English, - axial%20resolution

In synthetic aperture radar(SAR) imaging, microwave pulses are transmitted by an antenna towards the Earth surface. The microwave energy scattered back to the spacecraft is measured. The SAR makes use of the radar principle to form an image by utilising the time delay of the backscattered signals. In real aperture radar imaging, the groud resolution is limited by the size of the microwave beam sent out from the antenna. Finer details on the ground can be resolved by using a narrower beam. The beam width is inversely proportional to the size of the antenna, i. e. the longer the antenna, the narrower the beam.  2, record 37, English, - radar%20pulse

Record number: 39, Textual support number: 1 CONT

The incidence angle is commonly used to describe the angular relationship between the radar beam and the ground, surface layer or a target. A change of the radar illumination angle often affects the radar backscattering behaviour of a surface or target. The incidence angle changes across the radar image swath; it increases from near range to far range. In the case of satellite radar imagery, the change of incidence angle for flat terrain across the imaging swath tends to be rather small, usually on the order of several degrees. In the case of an inclined surface(slope), the local incidence angle is defined as the angle between the incident radar beam and a line that is normal to that surface. The local incidence angle determining, in part, the brightness, or image tone, for each picture element(pixel) and slope facet, is a key element in the prominent rendition of terrain features in radar imagery.  3, record 39, English, - incidence%20angle

Record number: 40, Textual support number: 1 CONT

Le signal reçu du nadir est une forte réflexion spéculaire de cibles situées à très faible distance en portée. Il en résulte sur l'image des tons très brillants. À cause de la compression des impulsions, le signal puissant se restreint à un petit nombre de pixels en portée. Sur les images à faisceau unique, les ambiguïtés de nadir peuvent apparaître près de la bordure des images en mode large, obtenues en temps réel ou au centre des images. Dans cette opération, les opportunités d'attraper une petite caractéristique spécifique digne d'intérêt sont rares pour ne pas dire inexistantes.  2, record 40, French, - ambigu%C3%AFt%C3%A9%20sur%20le%20nadir

"Precision Map Image" products have even greater positional accuracy than "Map Image" products. Ground Control Points (GCPs) as well as a map projection are used to spatially align the image. To order a "Precision Map Image" product, ground control points from a map or provided through Global Positional Satellite (GPS) technology are required. To further enhance the positional accuracy of the image, Digital Elevation Models (DEMs) can be used to correct terrain distortions. A DEM at sufficient detail will be needed to provide ortho-correction services.  2, record 42, English, - %5C%22Precision%20Map%20Image%5C%22%20product

"Path Image Plus" uses smaller pixel spacing than "Path Image" to retain full RADARSAT beam mode resolution. This will enhance your ability to make detailed analyses of point targets(e. g., ships, isolated buildings), linear features(e. g., pipelines, drainage networks), or to obtain subsequent spatial information if required. However, it will create a digital file that is considerably larger than a "Path Image" product.

The Multi-look fine beam modes image in the same swath locations as the fine beam modes with approximately the same spatial resolution. However, with multiple looks, the multi-look fine beam mode product has improved radiometric resolution. The high data rate capacity of the recorders means that the multi-look data can be obtained without a reduction in swath width. As with the fine beam modes, beams image in the incidence angle range of 30 to 50 degrees. Multi-look fine beam mode images are generated in a single polarization.  1, record 47, English, - multi%2Dlook%20fine%20beam%20mode
