Abstract
Underwater imaging is a challenging topic in the field of photography due to the absorption and scattering of light by water, which reduces the imaging distance and visibility. In this paper, the effects of seawater on the quality of ghost imaging (GI) are analyzed theoretically and experimentally. Our results indicate that GI technique, to a certain extent, can achieve better imaging quality than conventional imaging, especially under weak light condition in seawater environments. The compressed sensing ghost imaging (CSGI) can further enhance the visibility of ghost images with fewer measurements. Therefore, ghost imaging has the potential of realizing longer-distance underwater imaging, owing to its robustness against seawater environmental disturbance.
