Simultaneously, non-uniform time slice is used to quickly obtain 3DGI on an interesting target. In this approach, finite difference is beneficial to improving sensitivity of zero crossing to accurately obtain the position of the target in the field of view. This paper reports a novel structure based on non-uniform time slice combined with finite difference. The performance of 3DGI based on a uniform time slice is difficult to improve because obtaining an accurate time-slice position remains a challenge. ghost imaging (3DGI) using a detector is widely used in many applications.
