| The 21st century is the world large-scale development use marine resource, the expanded sea industry, the development marine economy new time. The submarine laser image formation technology takes the undersea detection the important means that in the underwater topography landform's plan, the submarine archaeology, the sea lifesaving, the underwater operation monitoring, the dike safe hidden danger examination, the seabed sunken wreck and domains and so on airplane wreckage survey is playing the influential role. As a result of marine environment complexity, sea suspended particle optical scattering characteristic not only immediate influence laser in sea water transmission characteristic, moreover is the marine environment optics monitor important rationale, the research sea water the laser image formation survey has the very vital significance to light diffusion properties adding water under. This article has carried on the theoretical analysis and the experimental study to the sea water optical char.The Mie scattering theory applies in the sea water the suspended particle diffusion properties inferential reasoning and the computation is this article key discussion's content. Gives the Mie scattering the first rationale, then has inferred the Mie scattering expression, and gives the initial condition, the computational method and the conclusion. Finally applies separately the Mie scattering theory in the submarine aerosol small granule and the big granule diffusion properties research, and gives the simulation result.This article's research technique and the experimental result, under adding water corresponded, technologies and so on survey and image formation have provided certain rationale and the experimental verification. |
