An analysis of Fresnel images of the amplitude binary diffraction grating with open ratio α/d < 0·5 is presented. Particular attention is paid to images appearing behind the self-imaging grating at distances z = 0 to d 2/λ. An attempt is made at a systematic examination of Fresnel images that have the form of binary gratings with ratio α′/d′ different from that of the original grating.
