An efficient way of reconstructing holographic images with simple light sources has been devised by two engineers at IBM's systems development laboratory. Robert H. Katyl and John H. King, Jr., think the technique might be applicable in future holographic data storage systems where an array of reliable, inexpensive light sources would be needed to read out the images of stored information.
