针对不同环境条件下海水中的气泡幕对后向散射光强以及偏振度的影响规律问题，基于矢量 Monte Carlo方法对整个模型进行仿真。在仿真过程中，充分考虑光子在气泡幕中的运动过程，对比分析了圆偏振光入射不同气泡半径、不同气泡密度和不同气泡幕宽度以及线偏光不同角度入射下，回波信号在强度和偏振度特性上的差异性；同时验证了激光海水气泡幕偏振探测法用于激光通信探测领域的可行性。

Aiming at the polarized light effect of different environment bubble group is degree of polarizationand backscattering light intensity，the simulation model using Monte Carlo method is built. In the simulation pro.cess, the motion process of photo in the group of bubble is fully considered. The difference of the characteristics ofthe backward scattering light intensity and the degree of polarization are compared and analyzed when the polarizedlight incident into the water in different bubble radius, bubble density and the width of bubbles. The feasibility ofwater bubbles in laser incident polarization detection method used in optical communication detection field is veri.fied and the application importance in this area is presented.
