Self-Reconstruction Property of a Special Speckle Pattern after Obstructing by an Opaque Obstruction

Figure 5

The simulation of speckle pattern and corresponding to the autocorrelation for different shape of obstruction with ; . The shape of the obstruction is circle (a1), equilateral triangle (b1) and square (c1). The first row denotes the speckle pattern in the source plane, the second row denotes the speckle pattern in the plane of , and the third row denotes the autocorrelation of the speckle pattern in the second row.
