title: Simplified production of spatial inverse filters.
abstract: A logarithmic nonlinearity in the transmittance-versus-exposure curve of a photographic material can greatly simplify holographic fabrication of inverse filters. We present here two filter-production methods utilizing this non-linearity, which produce relatively high-dynamic-range inverse filters. Confirming computer simulations and coherent-optical experiments are presented.
