摘要： Disclosed in a method and arrangement for performing a spatially resolved non-collinear measurement of the autocorrelation function of the first or higher order by means of a matrix of beam shaping individual elements, such that there is a local splitting of the beam into a beam matrix of conical component beams, where each component beam represents spatially integrated information regarding the partial area of the matrix through which it passes, the interference resolution is thus determined by the matrix geometry, and the interference pattern produced in space by each component beam in a certain plane imaged on a matrix camera supplies an autocorrelation function of the first order or, by utilizing non-linear interactions in a suitable medium, of a higher order accordingly, so that the coherence time or the pulse period of individual laser pulses or trains of multiple laser pulses can be determined as a function of location.

摘要： Searching for documents using different sources includes receiving a search statement containing information for the documents, and determining a search strategy based on the search statement. The search strategy includes first and second search activities for searching first and second sources, respectively, where the first and second search activities are weighted. The first and second sources are searched using the first and second search activities, respectively, where an order in which the first and second search activities are performed is dictated by weightings of the first and second search activities.
