通过检测后的瞬时强度的空间低通滤波的亚瑞利分辨率鬼成像实验进行。实现了超分辨率再现像，其空间分辨率超过瑞利衍射极限两倍以上。分辨率取决于滤波器阈值，并且对于广泛的阈值选择，可以超过瑞利极限。该设置简单且易于实现，这对于实际应用是有利的。
A sub-Rayleigh resolution ghost imaging experiment is performed via post-detection spatial low-pass filtering of the instantaneous intensity. A super-resolution reconstructed image has been achieved, in which the spatial resolution can exceed the Rayleigh diffraction limit by more than a factor of two. The resolution depends on the filter threshold, and the Rayleigh limit can be exceeded for a wide choice of threshold values. The setup is simple and easy to implement, which is an advantage for practical applications.
