摘要

Multipath effect in communication system is important to the quality of signals. The influence of the multipath effect on the performance of ghost imaging is investigated numerically and experimentally. The reflected light from ground glass is used as the light source to trigger the multipath effect, and we compare it with the traditional ghost imaging using transmitted light from ground glass as the light source. To compare the influence of the multipath effect, ghost imaging using reflected light from the aluminized ground glass under different distances is presented. The multipath effect is affected by the complexity of mutual interference, and it has both constructive and destructive influence on the quality of ghost imaging. The strong multipath effect increases the resolution, but it also reduces the signal-to-noise ratio of the reconstructed images.
