Abstract
In this paper we discuss our most recent work in two-dimensional nonspatial filtering. A brief introduction describes nonspatial filtering and its relationship to conventional spatial filtering. We then show results from our initial experiments in two-dimensional nonspatial filtering and briefly describe a more advanced design. A variation on the more advanced design demonstrates wavelength-independent operation. We then review our initial findings on adhesives appropriate for implementation of the advanced design and comment on the surface quality requirements of the recording material, a polymer with diffusion amplification (PDA). Finally we compare the robustness and efficiency of nonspatial filters with conventional spatial filters.
