We describe a new type of associative holographic memory and some related results. The memory can retrieve overlapping images which are stored in a volume hologram. The storage and retrieval of more than one image is demonstrated for the first time. The important role of thresholding in assuring ‘‘clean’’ retrieval is demonstrated.

    In electron holography, an abrupt reversal of contrast from white to black may occur in a digitally reconstructed phase image, potentially resulting in inaccurate phase information. There are two types of such abrupt reversals. One is a phase jump of 2Ï€ during the digital reconstruction...
