Examples of fresnel diffraction on an aperture (diaphragm,pinhole). A round aperture is placed in the path of a Gaussian beam emitted by a laser. The resulting diffraction pattern is observed on a screen some distance away. The image on the far right shows a central bright spot in the fresnel diffraction of a shadowgram.
