Optics Letters
|June 30, 2023
Summary
We present a novel imaging technique using the Hanbury Brown-Twiss approach to recover phase information through dynamic scattering media. This method reconstructs objects hidden behind diffusers by analyzing light intensity correlations.
Area of Science:
- Optics and Photonics
- Wave Phenomena
- Image Reconstruction
Background:
- The Hanbury Brown-Twiss (HBT) approach correlates intensity fluctuations to reveal light properties.
- Imaging through dynamic scattering media remains a significant challenge in optics.
Purpose of the Study:
- To propose and experimentally demonstrate a new imaging and phase recovery technique.
- To utilize the HBT approach for object reconstruction behind dynamic diffusers.
Main Methods:
- Theoretical framework development for HBT-based imaging.
- Experimental validation using dynamic scattering mediums.
- Exploitation of temporal ergodicity in scattered light for correlation analysis.
Main Results:
- Successful demonstration of phase recovery through dynamic scattering.
- Reconstruction of an object obscured by a dynamic diffuser.
- Validation of the theoretical model with experimental data.
Conclusions:
- The proposed HBT-based technique offers a viable solution for imaging in complex scattering environments.
- Temporal ergodicity is effectively leveraged for robust phase retrieval and object reconstruction.
