Abstract

Optical imaging is a crucial and direct technique to obtain information, and plays a pivotal role in science and technologies. However, in practical environments, the presence of fog can degrade quality of image, to even invisible. To reconstruct clear images in the presence of fog remains a daunting task in the field of optical imaging. Ghost imaging can suppress noise that is uncorrelated to illumination. This significantly enhances imaging robustness under noisy environment. In this paper, we built a time-gated computational ghost imaging system and evaluate the capability to reconstruct image under weak echoes. Furthermore, we use the imaging system to obtain clear pictures in foggy environments.
