摘要：
In this work we investigate a computer-generated hologram–interferogram between a tilted plane wave and a conical wave with a singularity of order p in azimuthal direction of its phase wave front, as a diffractive optical element when being illuminated by a Gaussian laser beam. It is similar to the fork-shaped hologram, except, now the fork-shaped dislocation is curved. The diffracted wave field amplitudes and intensities are calculated and analyzed in the process of Fresnel diffraction.
