  In addition to the optical aberrations, the magnitude of the optical cells of
detectors is one of the most important parameters, which restricts the
resolution of detectors. Adaptive optic and the methods of reducing the
aberrations are often used to increase the resolution of optical systems. In
the best situation the image structures, which are larger than the magnitude of
the cells, are detected and the finer structures are removed. In this paper, a
new method for increasing the resolution of images is presented. In this
method, the cells will scan the images by a piezoelectric crystal. The
piezoelectric crystal moves the cells in n identical steps. In each step, cells
move 1/n of the cell magnitude and the data are recorded. Finally, data are
analyzed and the structure of images is reconstructed. In this method, the
structure of images is n times finer than the cells magnitude.
