A periodic object image self-restoration in Talbot's planes

The effect of the periodic object image self-restoration in Talbot's planes was experimentally studied. Comparative investigation of the image parameters in paraxial area and in side lobes of diffraction is made. The images in side lobes have more high resistance against damages of an initial object it is proved. On the basis of these investigations, mechanisms which influence to deterioration of images in paraxial area and in side lobes are offered.
