High-resolution ghost imaging through complex scattering media via a temporal correction.

Area of Science:

• Optics and Photonics
• Quantum Imaging

Background:

• Conventional ghost imaging (GI) theory based on spatially correlated beams is insufficient for complex scattering environments.
• Existing GI methods struggle with dynamic and highly scattering media, limiting their practical applications.

Purpose of the Study:

• To develop and validate a high-resolution ghost imaging technique capable of penetrating complex scattering media.
• To complete the theoretical description of temporal correction for beam correlations in GI.
• To demonstrate the efficacy of the proposed method in challenging optical environments.

Main Methods:

• Implementation of a rectified temporally corrected beam correlation algorithm.
• Optical experiments utilizing complex, dynamic, and highly scattering media.
• Comparative analysis against conventional GI techniques.

Main Results:

• High-resolution ghost images were successfully retrieved even in complex, dynamic, and highly scattering environments.
• The proposed method significantly enhances ghost image quality with an increasing number of realizations.
• Conventional GI methods failed to retrieve images under the same experimental conditions.

Conclusions:

• The rectified temporally corrected beam correlation algorithm provides a robust framework for high-resolution GI through complex scattering media.
• This advancement overcomes limitations of conventional GI, enabling new applications in challenging wave propagation scenarios.
• The findings represent a significant step towards broader applications of GI in diverse free-space environments.
