This paper presents a formal solution to the problem of object restoration in a one-dimensional, diffraction-limited imaging system. It is found that if the illumination in the object space is confined to a finite region, then the imaging equation can be solved for the object in terms of the image. The solution can be expressed as a series expansion on the eigenfunctions of the imaging operator.

  5. The point response given by Eq. (2) describes an imaging system with unity magnification. This involves no loss of generality since it is always possible to normalize the image-plane coordinate so that the magnification is unity.
