光的分支流现象散开角度的研究

Study on the Angle of Light Branching Flow Phenomenon

光支流现象是激光在肥皂膜介质中传播而产生的一种特殊的光散射现象.肥皂膜作为可以产生光支流现象的介质未来有望成为新型实验平台,因此,研究光支流现象与肥皂膜之间的关系具有重要的科学意义.系统研究不同条件下的光支流散开角度的统计分布规律,结果表明光支流的散开角度呈高斯分布.实验中,通过改变激光入射角度,发现光支流的形态和散开角度与液膜的厚度分布、变化幅度的大小等因素有关.此外,光支流的散开角度还与皂液中蔗糖质量浓度成正相关.该研究结果将为光支流现象在医学诊断、液膜检测等方面的应用提供了更多可能性.

The light branched phenomenon is a special light scattering phenomenon produced by the propagation of laser light in soap film medium.The soap film,as a medium that can produce light branched phenomenon,is expected to become a new experimen-tal platform in the future.Therefore,it is of great scientific significance to study the relationship between the light branched phenome-non and the soap film.We systematically studied the distribution for the scattering angle of the optical tributaries under different condi-tions and found that the scattering angle of the optical tributaries has a Gaussian distribution.Furthermore,the characteristics and mag-nitude for the variation of the morphology and scattering angle for the optical tributaries with the thickness of the liquid film were ob-tained by changing the laser incidence angle.In addition,the scattering angle of the optical tributaries was positively correlated with the sucrose concentration in the soap solution.These results provide more possibilities for the application of the photo-branching phe-nomenon in medical diagnosis and liquid film detection.
