Although the scanning mirror rotates at a constant speed, the IFOV [instantaneous field of view] of the sensor moves faster(relative to the ground) and scans a larger area as it moves closer to the edges. This effect results in the compression of image features at points away from the nadir and is called tangential scale distortion.  1, record 1, English, - tangential%20scale%20distortion

Même si le miroir permettant le balayage tourne à une vitesse constante, le CVI [champ de visée instantané] du capteur se déplace plus rapidement par rapport à la surface et capte une région plus grande lorsqu'il se déplace près des bords de l'image. Cet effet produit une compression des caractéristiques de l'image pour les points éloignés du nadir et s'appelle distorsion tangentielle d'échelle.  1, record 1, French, - distorsion%20tangentielle%20d%27%C3%A9chelle

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 3, English, - spatial%20effective%20resolution%20element

[The] push-broom scanner [is a] type of imaging system... commonly used in optical remote sensing satellites such as SPOT. The imaging system has a linear detector array(usually of the CCD type) consisting of a number of detector elements(6000 elements in SPOT HRV). Each detector element projects an "instantaneous field of view(IFOV) "on the ground. The signal recorded by a detector element is proportional to the total radiation collected within its IFOV. At any instant, a row of pixels are formed. As the detector array flies along its track, the row of pixels sweeps along to generate a two-dimensional image.  2, record 4, English, - linear%20detector%20array

La mission d'observation est réalisée par un instrument à barrette CCD [charged-coupled device] de type «push-broom» avec une visée au nadir : sous l'effet du défilement du satellite sur son orbite, une barrette de détecteurs carrés disposés en ligne acquiert successivement les différentes lignes permettant de reconstituer une image. La taille de chaque détecteur élémentaire et la période d'échantillonnage sont ajustées de telle manière qu'en une période d'échantillonnage le point subsatellite se déplace de la projection au sol d'un détecteur au nadir.  2, record 4, French, - barrette%20de%20d%C3%A9tecteurs
