Abstract
Propagating electromagnetic light fields between nonparallel planes is of special importance, e.g., within the design of novel computergenerated holograms or the simulation of optical systems. In contrast to the extensively discussed evaluation between parallel planes, the diffractionbased propagation of light onto a tilted plane is more burdensome, since discrete fast Fourier transforms cannot be applied directly. In this work, we propose a quasifast algorithm (ON 3 log N ) that deals with this problem. Based on a proper decomposition into three rotations, the vectorial field distribution is calculated on a tilted plane using the spectrum of plane waves. The algorithm works on equidistant grids, so neither nonuniform Fourier transforms nor an explicit complex interpolation is necessary. The proposed algorithm is discussed in detail and applied to several examples of practical interest.
