A sensor made up of a linear detector array of CCDs (Charge Coupled Devices) that obtains data in the platform's direction of motion (azimuth or along-track dimension). 2, record 1, English, - along%2Dtrack%20scanner
Record number: 1, Textual support number: 1 CONT
Along-track scanners also use the forward motion of the platform to record successive scan lines and build up a two-dimensional image, perpendicular to the flight direction. However, instead of a scanning mirror, they use a linear array of detectors located at the focal plane of the image formed by lens systems, which are "pushed" along in the flight track direction (i.e. along track). These systems are also referred to as pushbroom scanners, as the motion of the detector array is analogous to the bristles of a broom being pushed along a floor. 3, record 1, English, - along%2Dtrack%20scanner

Principe de fonctionnement d’un système à barrette de détecteurs. [...] Le balayage est donc longitudinal à la manière d’un balai poussé devant soi, d’où l’expression «push broom» employée par certains auteurs. Comme les détecteurs sont tous de la même dimension et disposés parallèlement au sol, les tachèles sur le terrain sont également identiques s’il n’y a pas de distorsions optiques dans l’objectif. 3, record 1, French, - dispositif%20de%20balayage%20longitudinal
Record number: 1, Textual support number: 2 OBS
Le balayage perpendiculaire à la trajectoire ratisse la Terre en une série de lignes. Le balayage s’effectue d’un côté du capteur à l'autre, en utilisant un miroir rotatif. La radiation atteignant le capteur est divisée en plusieurs composantes spectrales qui sont détectées séparément. L'UV, le visible, le proche infrarouge et l'infrarouge sont séparés selon leurs longueurs d’onde. Un ensemble de détecteurs internes, sensibles à chacune des bandes spectrales, mesurent et enregistrent l'énergie en convertissant le signal électrique produit par les détecteurs en données numériques. 4, record 1, French, - dispositif%20de%20balayage%20longitudinal

Dans tous les systèmes d’analyse vidéo, le mouvement est décomposé en une série d’images fixes. Chaque image fixe est découpée en un certain nombre de lignes, elles-mêmes analysées successivement point par point de la gauche vers la droite. Ce principe d’analyse est appelé balayage vidéo. Celui-ci est identique de la prise de vues à la reproduction sur écran. Il constitue le premier niveau de standardisation d’un système vidéo. Le nombre d’images fixes analysées par seconde doit être supérieur à 16 images/seconde pour reconstituer une impression de mouvement. On a choisi des valeurs en relation avec la fréquence du courant électrique alternatif, soit :-25 images/seconde en Europe, en Afrique, au Moyen-Orient, dans une partie de l'Asie,-30 images/seconde pour les Amériques et le reste de l'Asie. 3, record 4, French, - image

A type of scanning mechanism that utilizes a CRT-generated beam of light to raster-scan a stationary document mounted on a flatbed platen. Through lens optics, the reflected beam of light is focused onto a photomultiplier and is converted into an electrical signal.
