摘要:

在传统的重影成像(GI)中,通过将电荷耦合器件(CCD)处的参考强度波动与桶检测器处的信号强度波动相关联来检索图像。在这篇文章中,我们提出了GI的协议,它被称为二阶累积量鬼成像(SCGI)。该方法利用两个探测器上光强起伏的相关性信息进行图像检索,比传统的梯度成像方法提高了分辨率。SCGI的实验结果与理论结果一致。

英文摘要:

In the conventional ghost imaging (GI), the image is retrieved by correlating the reference intensity fluctuation at a charge-coupled device (CCD) with the signal intensity fluctuation at a bucket detector. In this letter, we present the protocol of GI, it is called Second-order Cumulants ghost imaging (SCGI). The image is retrieved by the fluctuation information of correlating intensity fluctuation at two detectors, and the resolution limit can be enhanced than conventional GI. The experimental results of SCGI agreement with theoretical results.
