Special class of all-optical holographic associative memories with a nonlinearity in the filter domain is represented. Natural nonlinearity, just a nonlinear part of a holographic recording, lies in the basis of auto- and heteroassociative processes. It is shown, that the here developed class of quadric hologram-based associative memories is the widest generalization of a holographic matched filter technique including informative properties of ghost-image holography, Vander Lug's correlator, so-called 'second-order holography' using photorefractive oscillators, and nonlinear holographic associative memories based on resonator-like architectures. Potentialities of a quadric hologram-based associative processor to archival data storage and implementation of optical interconnections are discussed.
