We review and analyze several different methods of fabricating periodic, Fourier-transform type computer-generated kinoform holograms with the aim of using them as fan out elements in digital optical computing/optical processing systems. It is concluded that none of the presently known recording techniques or materials are suitable for producing an on axis kinoform with the required accuracy in its phase relief structure. The fabrication of a certain modified, but essentially equivalent, type of kinoform is however feasible. This involves a microlithographic process yielding an eight-level surface relief profile.
