Ghost imaging through turbulent atmosphere

WebWe present a series of results acquired at a 2-kilometer distance using our lidar system under several weather conditions, clear, cloudy, light rain, moderately foggy, and night. The experimental results show that ghost imaging lidar via spar-sity constraints can realize imaging in all these weather conditions. Keywords WebMay 30, 2024 · The ghost imaging system in transparent liquid is shown in Fig. 1. The pseudothermal source is prepared by illuminating a pulsed Nd:YAG laser into a slowly rotating ground glass. A nonpolarizing beam splitter (BS) splits the incident thermal light beam into two beams.
