<p>It comprises a sensor (7) comprising a first surface (4) provided with a two-dimensional array of photosensitive cells (6) and a second, opaque surface (5) arranged opposite the first surface, in which an orifice (8), also two-dimensional, is made in order to form an image of the light source on the said array, and computing means for computing the azimuth and the height of the source from the outputs of the said photosensitive cells, the said computing means being arranged in order to determine the centre of the image of the light source formed on the array of cells and in order to calculate therefrom the azimuth and the height of the said source. <IMAGE></p> |
