Antibunching and superbunching photon correlations in pseudo-natural light
Fig. 1. (a) Schematic diagram of the PBS model: two CMOS-based image sensors (detectors) for recording intensity correlation. When the detector in the black-dotted box is replaced with an object and a bucket detector, the setup can facilitate GI experiments. A programmable SLM is utilized to generate the PF of the wavefront with adjustable coherence time. A 4-f lens system (not shown) is used to image the SLM plane onto the detection plane. (b) Schematic diagram of GI for pseudo-natural light: an ordinary BS is introduced to obtain additional reference beam for division and subtraction operations. P, linear polarizer; HWP, half-wave plate; L, lens; RGG, rotating ground glass.
