1. A nano-imaging apparatus comprising multiple optical elements of sub-micron, nanometer scale, said optical elements functioning as lenses and have more than one pixel per optical element, said optical elements gathering overlapping information, said optical elements being supported onto a partly or fully radiation transmitting layer, which in turn is situated on top of a radiation sensitive layer being patterned so that under each of said optical elements there exists at least more than one radiation harvesting element that may be individually affected by radiation, whereby an image is obtained by combining said overlapping information.
