Abstract (en)
The width (lo, ... l3, ...) of the sources (Co, ..., C3d, C3g...) of this array increases progressively from the centre of the array (2) towards its ends. Moreover, these sources are arranged, with respect to one another, in such a way that this array exhibits no gaps in illumination. <IMAGE>
