Abstract

We present a novel structure based on differential optical path (DOP). The performance of three-dimensional ghost imaging (3DGI) is improved by DOP with high sensitivity and suppressed common noise because of the benefits of extracting zerocrossing point (i.e., interesting target position). Simulation results agree well with the theoretical analysis. Moreover, the relation between time slice and the signal-noise-ratio of 3DGI is discussed, and the optimal differential distance is obtained, thus motivating the development of a high-performance 3DGI.
