Second-order cumulants ghost imaging
Fig. 1. Experimental setup to assess the resolution of GI. There is a digital micro-mirror device (DMD) in the source. The light illuminates the object and then is collected by a bucket detector (Dt) with no spatial resolution.
Fig. 2. PSF of a pinhole object at α′ = 0 for λ = 550 nm, z = 0.8 m, and R = 0.001 m by traditional GI (blue solid curve) and SCGI (red dash curve).
Fig. 3. Image of the two-pinhole object by SCGI when α′ = −0.1 mm, α′′ = 0.1 mm, λ = 550 nm, R = 0.001 m, and z = 0.8 m: (a) L(α) = 0; (b) L(α) ≠ 0.
Fig. 4. Experimental results for a double slit: (a)–(d) show results by traditional GI, SCGI [κ2(α) of traditional GI], CSGI, and SCGI [κ2(α) of CSGI], respectively.
