Abstract

Results of an investigation of a referenceless hologram (RLH) associative response showing spatial variant brightness and signal-to-noise ratio (SNR) at the ghost image are presented. When an information page is one-side blocked, brightness and SNR are reaching their maximal magnitudes at the periphery of a ghost image, gradually decreasing as a running point approaches the readout fragment boundary. Spatial inhomogeneity of optical characteristics of the RLH's associative responses is explained with account of the singularity of an object field's power spectrum at the lowest spatial frequencies. Associative responses reconstructed by RLHs and some generalized holographic associative memories are compared.
