An associative memory is implemented by using a binary phase-only filter as the memory element in a two-focal-length (2-f) correlator architecture. A sharp autocorrelation peak, combined with the 2-f architecture, allows the noise to be separated adequately from the signal such that a simple plane mirror can be used in the correlation plane instead of a nonlinearity.
