Abstract:
1. A scanning multispectral telescope comprising: an optical architecture arranged so as to focus the image of an object in the vicinity of a photodetection assembly, the area of focus being an image plane; said photodetection assembly comprising a number of parallel rows of photodetectors, each row being dedicated to a particular spectral band, each spectral band being centred on a mean wavelength; means for acquiring and analyzing the images obtained from the rows of photodetectors, said means comprising a phase diversity algorithm; wherein the telescope comprises optical or mechanical means arranged in such a way that at least one of the rows of photodetectors is offset by a fraction of the mean wavelength which corresponds to the associated row of photodetectors on an axis perpendicular to the image plane, the rows of photodetectors being situated in a same plane inclined by a determined angle relative to the image plane, the inclination taking place about a direction parallel to the rows of photodetectors.
