Simulation integrates scattering and turbulence effects on laser transmission, highlighting complex interactions.

The aim is to explore how scattering and turbulence affect laser beam propagation and intensity fluctuations.
Developed a coupled model integrating the Monte Carlo method and multi-phase screens.
Derived an analytical formula for single-scattering scintillation index (SI).
Established a composite SI expression using the scattered-to-transmitted light intensity ratio.
Proposed sinusoidal and logarithmic compensation models to address visibility and turbulence deviations.
Revealed that turbulence enhances intensity fluctuations and increases the scintillation index.
Demonstrated that higher scattered light proportions stabilize the scintillation index.
Validated the model's effectiveness in simulating interactions between scattering and turbulence.

Wang et al. (2026) studied this question.
