The quality of depth maps acquired by a time-of-flight three-dimensional ghost imaging (3DGI) system is limited by dynamic ambient light and electrical noise. We developed a novel method that integrates the differential-correlation-sampling (DCS) method and a modulated continuous-wave laser source to realize the 3DGI and reduce the noise influence. The simulation results for the proposed method, DCS-3DGI, verify its feasibility. The analysis of mean-square-error, peak signal-to-noise ratio, structural similarity index measure, and edge preservation index demonstrates a superior anti-interference performance than conventional 3DGI methods.
