摘要：

An application of two photorefractive crystal fibers connected in cascade to heteroassociative memory is experimentally demonstrated. The crystal is iron-doped lithium niobate. The crystal fiber parameters are 1 mm x 1 mm in cross section and 5 mm in length. An angular multiple-recording technique is used to record Fourier-transformed images. It is shown experimentally that this fiber holography can be used as an alternative to bulk photorefractive crystals in optical memory devices.
