摘要：
A method is disclosed of improving the resolution of an imaging system in which radiation is detected and an image which is represented by a plurality of distributed signals is produced, wherein the method includes improving the signal to noise ratio of the image. Radiation is detected by a charge coupled device having a two-dimensional array of light sensitive detector elements and resolution is enhanced by sequentially masking discrete areas of each detector element with an apertured opaque mask chosen so as to allow for square (n x n) arrays of aperture elements for each detector and so that the apertures can be arranged as an embedded set which facilitate heirarchical refinement of the resolution.
