"Intensified CCD camera \u2013 A new tool of research of photon pairs generated in spontaneous parametric down-conversion" . "[D7EE47F78368]" . "For counting of photons we use a new tool: intensified single photon CCD camera. We compare the advantages and disadvantages of using the intensified CCD camera and classical detectors for photon counting. We have used the camera for a measurement of correlations in twin beams composed from photon pairs generated in spontaneous parametric downconversion pumped by strong ultra short pulses. From measured data we tried to reconstruct the state of the photons after leaving the crystal. The experimental data clearly show the nonclassical features of biphotons. Spatial correlations have been explored as well."@en . "3"^^ . . "Intensified CCD camera \u2013 A new tool of research of photon pairs generated in spontaneous parametric down-conversion"@en . .
