Claim:
1. An imaging device to be placed on board a satellite or an aircraft, comprising: an imaging optics, suitable for forming an image in a focal plane; at least two luminous flux detector arrays, each separately comprising: for each main detector, a first filter arranged for spectral filtering of the luminous flux reaching the first photosensitive elements of said main detector, with a first spectral transmission window; and for each additional detector, a second filter arranged for spectral filtering of the luminous flux reaching the second photosensitive elements of said additional detector, with a second spectral transmission window different from the first spectral transmission window for the same detector array, in which, for each detector array separately from the other detector array, the main detector and each additional detector are produced on one same single-piece substrate dedicated to said detector array, with the row of second photosensitive elements extending in the row direction over a second length comprised between 0.9 and 1.1 times the first length, and being offset with respect to the rows of the main detector parallel to the column direction, the respective substrates of the two detector arrays both being arranged in the same focal plane of the imaging optics, and oriented so that the respective column directions of said detector arrays are parallel to each other.
