Ghost Imaging: From Quantum to Artificial Intelligence

Dear Colleagues,

Ghost imaging is an alternative to conventional image capture with digital cameras, which can achieve greater sensitivity and/or resolution than classical optics utilizing correlation measurement. Ghost imaging has been demonstrated both with quantum light and classical light sources. It has been quickly adapted to other fields, including time domain imaging, X-ray imaging, THz imaging, and neutron imaging. In addition, with the advances in artificial intelligence, ghost imaging through deep learning has recently shown significant improvements in speed, resolution, and robustness. Recent developments in methods and techniques have made it possible to move from proof-of-principle to applications, such as biomedical imaging and earth and space science. Our intention is to present a variety of ideas, results, and discussions about ghost imaging in this issue. We hope this could be helpful to further research and practical applications of ghost imaging itself and research and practical applications in other fields.
