Figure | Principle of classical SHWS and PCB-SHWS.  a, classical SHWS. The inset shows a focused spot inside a microlens aperture. b, PCB-SHWS. At the microlens and its back focal plane respectively, two balls with the same color represent one entangled photon pair. A tilt phase leads to the centroid displacement. The inset is the biphoton centroid marginal distribution inside an aperture.
