### Abstract

Utilizing a new scheme with a single-photon-sensitive intensified CCD camera and a femtosecond laser, we have measured signal–idler correlations over the full cone of degenerate type I spontaneous parametric downconversion, thereby establishing wave-vector correlations in two dimensions. We discuss the key features of the camera that are important for its use in twin-photon correlation measurements.
