Reflection Ghost Imaging Based on Superimposed Speckle-Pattern
A reflection ghost imaging scheme based on the superimposed speckle pattern is proposed. The speckle particles of different sizes are randomly inserted into the speckle patterns with the speckle particle size of 1 pixel×1 pixel. The superimposed speckle pattern is applied as the illuminating source for ghost imaging. The numerical simulation and experimental results show that, compared with the traditional ghost imaging scheme, the superimposed speckle pattern formed by random mixing of speckle particles with different sizes significantly improves the contrast-to-noise ratio of the spatial information of the recovered object. The proposed scheme can not only reduce the number of samplings, but also significantly recover the image space information, and further promote the practical application of ghost imaging technology.
