<p>The device comprises a prismatic enclosure (CA), preferably with a rectangular base and open at the top side, and in the shortest sidewall of which is situated the real object (OR) and on top of the latter a mirror (EP), while two convergent mirrors (EC1 and EC2) are placed on its opposite side face, the focal points of the convergent mirrors coinciding and being situated on the geometric centre of the mirror (EP) so that the image of the real object (OR) is reflected first in the lower convergent mirror (EC2), then in the mirror (EP), then in the upper convergent mirror (EC1) and finally the tridimensional image (I) is obtained outside the enclosure (CA).</p> |
