Abstract

In this paper, we discuss our most recent work in 2D nonspatial filtering. A brief introduction describes nonspatial filtering and its relationship to conventional spatial filtering. We then show result from our initial experiments in 2D 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. Finally, we compare the robustness and efficiency of nonspatial filters with conventional spatial filters.
