A microwave lens that is based on the principles of holography is described. It consists of a zone plate, and it has been shown theoretically and experimentally that it has the limit of resolution, which is predicted by the aperture and the wavelength used. Another experiment was performed to compare the limit of resolution of a one-dimensional one with that of a plane zone plate. Finally the lens was used in an experimental setup to image a flat object.
