Abstract : The patent describes a technique for simultaneously generating and recording a correlation function by utilizing an intensity modulated beam of light or electrons directed onto a record medium in a scanning format is described and several methods of implementation are given. As the beam scans across any selected spot on the record medium, the correlation function appears in the form of record medium exposure in accordance with the temporal and spatial variations of the beam during its passage over the spot. This concept is described for two-dimensional correlation but can be used for one-dimensional correlation processing in either of the two dimensions available on the record medium.
