The key for Monte Carlo methods to simulate light propagation in seawater is to define the relation between random numbers and light propagation.First,the random numbers,which are pseudo random numbers from a uniform distribution and obtained from the computer,are transformed so that random numbers are distributed according to the functions which describe the scattering and absorption properties of the medium.The transformation describes the scattering and absorption properties of the medium.Second,the relative coordinate system after a scattering interaction is transformed into the absolute coordinate system before the light scattering.The conclusions can be obtained from the simulation whit Monte Carlo method:light scattered in the seawater looks like a horn,and photons are dense in the middle of the horn,whereas they dilute around gradually in the environment.
