a Input intensity image. The color bar depicts the number of total single-photon counts per pixel, which accumulate over acquisition time. Scale bar, 400 μm. b, c Input coincidences with single fixed pixel indicated by “X”, with pixel locations on spontaneous parametric down-conversion ring also shown in a. Color bars quantify coincidences per pixel. Scale bar, 400 μm. d All input coincidences projected into sum-coordinates ri + rj. Inset shows close-up of peak. Color bar quantifies coincidences projected into the sum-coordinates. Scale bar, 800 μm. e Cross-section along dashed white line in d, showing experimental values (black dots) and Gaussian fitting (solid red). f–j are analogous to a–e, respectively, and show coincidences after propagating through PSF.
