Beam spread function with time dispersion.
An analytical model for the beam spread function with time dispersion is modeled and validated against Monte Carlo calculations. The model, which is structured on simple statistical concepts and relies on only first and second moments for displacement, angle, and multipath time, is suitable for describing pulsed laser radiation propagation in nonconservative scattering media out to tens of scattering lengths. Numerical examples for marine environments are used to show its robustness and versatility.
