摘要：
本文描述了一种使用单个SPAD阵列同时作为几个像素的“桶”探测器和成像相机的鬼成像方法。该方法的关键点在于：根据每帧计数数量对用于鬼像重建的数据帧进行滤波，并叠加由不同“桶”像素获得的关联图像。成像实验使用赝热光源进行，光强低到暗计数对成像产生显著影响的程度。我们证明该方法能够显著降低暗计数对鬼像的破坏性影响，并提高图像对比度、空间分辨率以及图像与参考图像的相似度。
英文摘要：
An approach to ghost imaging with a single SPAD array used simultaneously as a several-pixel "bucket" detector and an imaging camera is described. The key points of the approach are filtering data frames used for ghost-image reconstruction by the number of per-frame counts and superposing correlation images obtained for different "bucket" pixels. The imaging is performed in an experiment with a pseudo-thermal light source where the light intensity is so low that the dark counts have a noticeable effect on imaging. We demonstrate that the approach is capable to significantly reduce the destructive effect of dark counts on the ghost image and improve image contrast, spatial resolution, and image similarity to a reference image.
