Any slowly varying 2-D space-variant system can, in principle, be represented holo-graphically by spatially sampling the input plane and multiplexing the respective system transfer functions. This paper describes an alternative multiplexing technique in which one samples in the Fourier plane to produce the multiplexed holograms. Various techniques for accessing any particular set of the multiplexed transfer functions are considered. Preliminary experimental results are also presented.
