摘　　要：为了系统的研究舰船尾流中气泡的激光前向散射特性,本文通过自行设计的试验系统模拟舰船尾流气泡.结合Mie散射理论和水下光散射特性,探讨了气泡幕激光前向散射特性.实验选用波长为632.8nm的激光,暗室内在不同介质以及不同气泡密度的条件下,测量了气泡幕的激光散射光照度.结果表明散射光照度主要分布在前向0°角附近,散射光与气泡的密度成反比,气泡密度低时外部光照对散射光影响更加明显.The self-designed experiment system was established to research the forward scattering properties of bubbles. The forward scattering by bubble films was analyzed combining with the Mie scattering theory and scattering characteristics of underwater light. The illumination of scattering light was measured under different media and bubble density in dark room with the laser wavelength 632.8 nm. The result shows that the illumination of scattering light mainly distributed around 0″ angle. The scattering light which is more pronounced with external light in the low pressure is inversely proportional with the pressure.
