We demonstrate the implementation of an optical intensity correlator using Bi12SiO20 (BSO) as a dynamic holographic medium. The advantages of this correlator are large tolerance in the placement of input objects and BSO crystal, and insensitivity to phase inhomogeneities in the readout portion. This allows readout to be conducted via a commercial liquid crystal television.
