$\begin{figure} \par\includegraphics[width=7.2cm,clip]{8659fig1.eps}\end{figure}$ Figure 1: Numerical illustrations. Left three figures: Fizeau imaging. Top: the array of 7 $\times$ 7 square apertures (side length 3 units, separation between aperture centers of 20 units); below: the object angular frequencies in the Fourier (modulus in a log scale); bottom: the direct image showing the object replication. Center three figures, from top to bottom: densified aperture for a separation reduced to 5 units, the Fourier plane showing the non-overlapping densified OTF (only the central non-zero part is shown) and the focal image. Right three figures: same as center for a full densification. The focal plane images are drawn at the same scale, and the zooming effect of Eq. (10) appears clearly.

$\begin{figure} \par\includegraphics[width=7.2cm,clip]{8659fig2.eps}\end{figure}$ Figure 2: Same array as in Fig. 1, but for a distance between apertures enlarged to 35. Left: Fizeau imaging showing the object replications. Center: densified apertures corresponding to a distance of 5 between apertures. Right: close-by densification 3. The overlapping of images is present in the Fizeau configuration and the image cannot be recovered.

$\begin{figure} \par\includegraphics[width=6.3cm,clip]{8659fig3.eps}\end{figure}$ Figure 3: Example of the result that can be obtained with a fully non-redundant array of 22 square apertures (side length 3 units, minimum distance between aperture centers 10 units). Left: Fizeau imaging. Right: hypertelescope configuration. From top to bottom: aperture, Fourier and focal plane.
