Figure 4

The averaged speckle background and the corresponding Gaussian-function-fitting result for the light focusing experiment demonstrated in Section 2. (a) The averaged speckle background for 200 measurements. (b) The intensity distribution for the averaged speckle background and the fitting result. The black triangles are the mean gray values for different radiuses, and the red line is the Gaussian-function-fitting curve on them.
