Abstract
We define a generalized Fresnel zone plate as a diffraction grating device that diffracts a predetermined wave front into a spherical converging one. The device is constructed as the intersection of a family of refracting profiles with an arbitrary shaped surface. The refracting profiles are obtained as envelopes of specific families of Cartesian ovals. The classical Fresnel zone plate is a particular case of this class. This construction has several interesting applications.
