Partial aperture imaging system

A partial-aperture imaging system, comprising:

• (a) one or more partial-aperture units, each partial-aperture unit comprising:
• one or more partial apertures that are disposed over a periphery of a circular area representing a full aperture having a diameter D, each of said partial apertures being directed towards a scenery, while the total area of all said partial apertures spans only a portion of said area of the full aperture;
• one coded phase mask (CPM) for each of said partial apertures, respectively, said CPM receiving one at a time, from a respective partial aperture at least one point-object image and at least one complex-object image, said CPM modulating respectively by a same random code the phases of pixels of one or more pairs of said point-object and complex-object images, thereby to form respectively point-object random images (PORIs) and complex-object random image (CORIs);
• an imager for optically receiving said at least one PORI—each PORI being defined as a PSF, respectively, and at least one CORI, and for storing in a memory;
• and
• (b) a processor for cross-correlating those pairs of PSFs and CORIs that have been randomly modulated by a same-code CPM, thereby to form a final image.
