Figure 2: Position and momentum correlation functions in the x′ dimension for an increasing number of images.
From: Imaging high-dimensional spatial entanglement with a camera
(a) Measured position correlations from imaging plane scheme. (b) Measured momentum correlations from far-field scheme. Blue circles represents the spatial-correlation and red squares represent the reference-correlation. The slight asymmetry of the far-field correlation function is the result of a non-uniform near collinear degenerate light cone.
