Abstract:
In an optical system having a detector means and processor means in which image data is obtained comprising noisy blurred scene data containing an object to be reconstructed (D1), and noisy blurred background data (D2) of the same scene, an improved method for increasing the spatial resolution of the imaging data produced by the diffraction limited optical system, the improvement therewith comprising:filtering the noisy blurred background data (D2) of the same scene to obtain noise suppressed data;applying estimations of point spread functions associated with the noise suppressed data and optical system and to estimates of the noise suppressed data to obtain a reconstructed background image (I.sub.r (x)); andlow pass filtering the noisy blurred scene data containing the object to be reconstructed (D1) and using the reconstructed background image (I.sub.r (x)) to eliminate the background data from said image data to obtain a reconstructed image of the object with increased spatial resolution.
