Macular surgery often requires high image resolution than is provided by the [wide-angle viewing systems]. In such a scenario, a macular lens is preferred to increase the magnification of the posterior pole for more delicate and precise surgical maneuvers, such as internal limiting membrane(ILM) and ERM [epiretinal membrane] dissection. These lenses provide a much smaller field of view, limiting their use to primarily posterior pole surgery. The view provided through these lenses is direct, thus inversion is not necessary.

Optical coherence tomography(OCT) is a non-contact imaging technique which generates cross-sectional images of tissue with high resolution. Therefore it is especially valuable in organs, where traditional microscopic tissue diagnosis by means of biopsy is not available—such as the human eye. Since OCT is completely noninvasive, it provides in vivo images without impacting the tissue that is imaged. Fast scanning rates and quick signal processing allows for image visualization in real time and at video rate.... the resolution of OCT is much higher than that of other medical imaging methods like ultrasound or magnetic resonance imaging(MRI).  3, record 5, English, - optical%20coherence%20tomography

synthetic aperture radar; SAR :[A] synthetic aperture radar(SAR) is a side-looking imaging radar usually operating on either an aircraft or a spacecraft. The radar transmits a series of short, coherent pulses to the ground producing a footprint whose size is inversely proportional to the antenna size, its aperture. Because the antenna size is generally small, the footprint is large and any particular target is illuminated by several hundred radar pulses. Intensive signal processing involving the detection of small Doppler shifts in the reflected signals from targets to the moving radar produces a high resolution image that is equivalent to one that would have been collected by a radar with a much larger aperture.  4, record 11, English, - C%2Dband%20synthetic%20aperture%20radar

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 12, 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 12, 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 26, 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 32, English, - axial%20resolution

For applications such as cartography, where it is important to precisely locate the correct position of features such as roads and boundaries, it has been difficult or impossible to evaluate the relative performance of different sensors through the standard specifications of IFOV [Instantaneous Field of View] or spatial resolution. In an effort to overcome this difficulty, a second concept... labeled spatial effective resolution element(SERE), is evolving. Although this concept is not fully developed, it provides an indication of the factors to be taken into account when attempting to correlate different systems. These factors include : surface area on the Earth, or its equivalent on the image plane, the IFOV and the spread function resulting from optical diffraction and aberrations as well as electronic lag or smear. Essentially, the concept of SERE is an attempt to determine the IFOV of the hypothetical, unsampled(ideal) scanning system which would yield performance equivalent to that of any given real sensor system. Whether such an equivalence exists is yet to be determined.  3, record 34, English, - spatial%20effective%20resolution%20element

The interest of a ground based Slit Aperture Telescope(SAT) which operates with a long thin pupil has been underlined for applications in the field of high angular resolution observations by speckle-interferometric techniques. The SAT lies halfway between the Michelson stellar interferometer and the standard telescope with circular aperture. The authors present the principle of an image processing algorithm which could be used associated with a space-SAT for astronomical image reconstruction. A full coverage of the two dimensional Fourier plane of the astronomical object can be obtained by rotating the SAT around its optical axis. The method of image reconstruction is analogous to those used in computerized tomography and uses Fast Fourier Transform algorithm. The interest of the use of a rotating space-SAT among synthetic apertures is its capability of giving a reconstructed image of the astronomical object simultaneously in several light wavelengths, each colored image being comparable with the others for fruitful astrophysical applications.  3, record 40, English, - slit%20aperture%20telescope

ScanSAR processing uses the Spectral Analysis(SPECAN) algorithm to produce full resolution images for RADARSAT ScanSAR data. PrecisionScan uses a range of image analysis functions to assess the quality of images produced, including : Point Target Analysis [;] Distributed Target Analysis [;] ScanSAR Analysis [;] Azimuth Ambiguity Ratio Analysis [;] Swath Characterization [;] Elevation Pattern Determination. These tools are based on the RADARSAT Calibration Workstation Array developed for the Canadian Space Agency.  3, record 45, English, - spectral%20analysis

L'application d'une analyse de texture combinée avec une analyse spectrale pour la classification des images SPOT se traduit généralement par une augmentation significative de l'exactitude de la classification, en particulier dans les milieux à texture variée, comme le milieu péri-urbain ou littoral (Marceau, 1989; Coulombe, 1990).  3, record 45, French, - analyse%20spectrale

Hard classification results in one class/pixel [as opposed to] soft classification [that] results in multiple classes/pixel, with associated likelihoods for each class.  3, record 46, English, - hard%20classification

Record number: 46, Textual support number: 2 CONT

If the resolution of the image is sufficiently high(e. g. 1m or less), it may be that each pixel will represent only one type of land cover, and so we can make an accurate ’hard’ classification. However, for lower-resolution images-the kind that are more readily available for different places and for different times-each pixel is likely to represent a mix of different land-cover types. As a result, a hard classification will probably represent only a part of the pixel and will inaccurately describe the remainder of the area covered by that pixel.  4, record 46, English, - hard%20classification

The azimuth direction is perpendicular to the range direction. The resolution of an image in the azimuth directions for a SAR image is constant and is independent of the range. For two objects to be resolved, they must be separated in the azimuth direction by a distance greater than the beamwidth on the ground.  4, record 47, English, - azimuth%20direction

A radar pulse is transmitted from the antenna to the ground. The radar pulse is scattered by the ground targets back to the antenna.  2, record 48, English, - radar%20pulse

Record number: 48, Textual support number: 1 OBS

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 48, English, - radar%20pulse

La génération d'une image SAR nécessite la combinaison de deux mécanismes de balayage. Tout d'abord un balayage latéral. Chaque impulsion se propopage à une vitesse égale à celle de la lumière (c = 3.108 m.s-1) selon la direction de visée du satellite (across track), l'écho reçu au niveau de l'antenne est ensuite échantillonné à la fréquence fe (18.96 Mhz pour ERS-1). Simultanément, la scène est balayée dans le sens de déplacement du satellite (along track) à la fréquence d'émission des impulsions notée fp ou PRD (Pulse Rate Frequency) : (entre 1640 et 1720 Hz, par pas de 2 Hz dans le cas d'ERS-1). Les échelles de grandeur des divers mécanismes mis en jeux étant différentes, nous pouvons les supposer indépendants entre eux. Le signal reçu peut être ainsi organisé dans une matrice bi-dimensionnelle, où les paramètres de temps et de distance sont représentés respectivement en ligne par le cadencement des impulsions (PRF) et en colonne par la position des échos sur la ligne, une ligne étant acquise à chaque émission d'une impulsion radar (ou pulse). Une colonne de l'image représentera l'ensemble des réponses des réflecteurs placés à une distance donnée de l'antenne (distance radiale). Sa position sur la ligne est linéairement liée au temps mis par l'onde radar à lui revenir après s'être réfléchie sur le point cible, le radar étant considéré immobile durant ce temps.  2, record 48, French, - impulsion%20radar
