Scientific paper

The method for carrying out the image reconstruction by means of the 2-dimensional discrete Fourier transform is introduced. A method for evaluating the optical transfer function by the spectrum fitting is also presented. The results obtained with the CCD system attached to the 1-m telescope show that the spatial resolution of the system increases by 275% and the binary stars that are mixed in the original image are obviously separated from each other after the processing.
