Abstract

Optical lensless methods of processing the periodic image based on the Talbot effect and Fraunhofer diffraction are considered. Regularities of making of image in nonzero orders of diffraction are shown and are explored their noise features. It is shown that without using lenses possible to produce a transformation of image of a periodic object in the Fourier-spectrum on end distances.
