摘要
提出了一种基于叠加散斑图的反射鬼成像方案。在散斑颗粒尺寸为1pixel×1pixel的散斑图上,随机插入不同尺寸的散斑颗粒,将叠加成的散斑图作为鬼成像的光源。数值模拟及实验结果表明,相对于传统的鬼成像方案,由多种不同尺寸散斑颗粒随机混合形成的叠加散斑不仅显著提高了恢复物体空间信息的衬噪比,还减少了采样次数,推动了鬼成像技术的实用化。
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.
