Simulating the Optical Phase Conjugation Phenomenon of Light Multiply Scattered through a Macroscopic Random Medium

摘要

The light scattering effects of turbid media causing opacity may be undone via Optical Phase Conjugation (OPC). Here we rigorously simulate light scattering through a macroscopic random using the pseudospectral time-domain (PSTD) technique. The OPC phenomenon of multiply scattered light can be quantitatively analyzed which is not feasible otherwise. Specifically, factors affecting the electromagnetic energy propagation and refocusing phenomenon is analyzed. The reported simulation study allows accurate characterization of the optical properties of the OPC phenomenon for practical biomedical applications.
