             abstract = "Optical microscopic images, especially with a nonconfocal 
                         microscope, are fundamentally limited because the optical transfer 
                         function (the Fourier transform of the point-spread function) is 
                         zero over a region of the spatial-frequency domain. Iterative 
                         algorithms were developed for the restoration and extrapolation of 
                         diffraction-limited imagery. In this paper we present the 
                         effectiveness of an iterative method based on the Richardson-Lucy 
                         algorithm for image restoration and a simultaneous modified 
                         version of Gerchberg-Papoulis method to extrapolate the spectrum 
                         and control the noise amplification. Good convergence 
                         stabilization results were achieved and also good numerical 
                         results were observed.",
