Abstrakt: Abstract: An intensified CCD camera is used as a detector to analyze the properties of correlated photon pairs obtained by spontaneous parametric down-conversion. Pixels of the camera serve as detecting elements so that the whole camera represents a massively multichannel photon-counter. This enables measurement of photon-number statistics of the signal and idler fields. Finite detection quantum efficiencies, noises as well as possible loss of one or both photons from a pair are taken into account. The joint signal-idler photon-number distribution is obtained using the expectation maximization algorithm. Spatial resolution of the camera allows for investigation of the spatial properties of correlations of the photon pairs. Area of correlation of the correlated photon pairs is determined.
