Area of Science:

• Optics and Photonics
• Computational Imaging
• Light Scattering

Background:

• Understanding scattered light fields is crucial for developing advanced imaging systems.
• Existing models often lack the ability to capture complex statistical properties of light propagation through scattering media.
• Simulating imaging schemes requires robust models that account for various optical phenomena.

Purpose of the Study:

• To incorporate statistical properties of diverse optical paths and photon interactions within the model.
• To enhance the simulation capabilities for imaging schemes, including field of view limitations and spectral characteristics.

Main Methods:

• Development of the Anisotropic Optical Path (AOP) model.
• Incorporation of statistical analysis of different optical paths and photon processes.
• Simulation of limited field of view (FOV) effects constrained by the memory effect.
• Modeling of spectral differences under broadband illumination.

Main Results:

• The AOP model successfully simulates limited fields of view (FOV) influenced by the memory effect.
• The model accurately reflects spectral variations in scattered light under broadband illumination.
• Demonstration of the model's capability for light field simulation in higher degrees of freedom.
• Verification of the feasibility of using scattering media as spectral filters based on speckle pattern decorrelation.

Conclusions:

• The proposed Anisotropic Optical Path (AOP) model provides a robust framework for understanding and simulating scattered light fields.
• The model enhances computational support for designing and evaluating imaging schemes.
• The findings confirm the potential of scattering media as effective spectral filters, opening new avenues in optical filtering technologies.
