ABSTRACT:
The invention concerns an imaging assembly comprising a synthetic aperture instrument including a plurality of pupils separated by sampling detection means. The sampling frequency values in column (u) and in line (v) are less than the values corresponding to the Shannon criterion, and are such that zones of response modulation transfer function resulting from sampling are inserted in zones of null modulation transfer function of the central section of the modulation transfer function, so that said zones do not form an intersection and, in a central section of smaller dimension (220) than the central section (200.0) of the modulation transfer function, the set of zones representing the central section of the modulation transfer function is present. The acquired image spectrum is reconfigured so as to reconstruct said image.
