面向背景的分层液体病例研究
背景导向纹影
来自维基百科的免费百科全书背景导向纹影（BOS）是一种利用流体密度和折射率之间的Gladstone-Dale关系对流体密度梯度进行流动可视化的新技术。
BOS通过消除使用昂贵的镜子，激光和刀刃的需要简化了可视化过程。在其最简单的形式中，BOS利用随机生成的点阵图形的简单背景图案，廉价的频闪光源和高速数码相机。
在其实施的初始阶段，它主要用作定性可视化方法。进一步研究开发该技术将实现流体流动的定量可视化，包括低温流动，超音速和高超声速流动，生物医学装置流动可视化等各种应用。

该软件主要由来自特拉维夫大学Alex Liberzon实验室的Lilly Verso编写，使用OpenPIV软件包作为平台。该软件利用OpenPIV Matlab软件包进行互相关分析（基本上是PIV分析的剥离版本）和OpenPIV - Poisson求解器思想的压力包。使用公共域Matlab代码测试了额外的泊松求解器。感谢这些软件包的作者。
