传统的灰度目标成像一般需要多比特检测，本文研究了基于二值检测的灰度目标鬼像成像，结果表明二值鬼像成像足以重建灰度目标。对于灰度值较低的目标，仅用二值信号重建时，二值鬼像与普通鬼像的重建结果相差不大，而对于灰度值较高的目标，二值鬼像重建的结果与普通鬼像基本相同。在极端情况下，根据重影成像的特点，利用二值化检测器可以得到灰度目标的图像。图形摘要
AbstractTraditional imaging of grayscale object generally demands multiple bits detection, in this paper, ghost imaging for grayscale object based on binary detection is investigated, and our results demonstrate that binary ghost imaging is enough to reconstruct the grayscale objects. With only binary signals, a little difference between binary and ordinary ghost imaging can be found when reconstructing the object with lower grayscale value, however, for the grayscale object with higher value, binary ghost imaging almostly achieves the same results to ordinary ghost imaging. Under extreme cases, the image of a grayscale object can be obtained by using the binary detector according to the characteristics of ghost imaging.Graphical abstract
