A Strategy for Improving the Quality of Ghost Imaging

Figure 5

Simulation results of the “cnu” image. (a) Original image. (b) Speckle pattern with uniform light intensity distribution. (c) Simulation result based on (b) (10,000 measurements). (d) Speckle pattern with uneven light intensity distribution (r = 3). (e) Simulation result based on (d) (10,000 measurements). (f) Simulation result obtained by the proposed method, that is, the uneven light field is only loaded in the object arm.
