Record number: 1, Textual support number: 1 DEF
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

Capteur constitué d'une barrette de DTC (dispositifs à transfert de charge) qui collecte des données dans le sens de l'orbite de la plate-forme (en azimut ou en trajectoire longitudinale). 2, record 1, French, - dispositif%20de%20balayage%20longitudinal
Record number: 1, Textual support number: 1 OBS
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
