Design of Dammann gratings for two-dimensional, nonseparable, noncentrosymmetric responses.
Dammann gratings are binary-phase Fourier holograms that are used to generate an array of point sources. Using symmetry and separability arguments, we extend Dammann's method for generating one-dimensional symmetric arrays to general two-dimensional responses. Computer-generated holograms are used to verify the modified design method.
