title: Design and demonstration of a new kind of aperture for getting expected diffraction patterns.
abstract: In the regime of Fresnel diffraction, a novel algorithm is proposed for aperture design for getting expected diffraction patterns. Experiments have verified the feasibility of this method. It may be used in beam transition, optics communication, information encryption, and other related fields.
